"We chose a wedding date and a location," Hannah revealed in the 20-minute video. "But we haven't figured out anything yet."
Hannah revealed that although she and Dylan live in San Diego, their August 2023 wedding will not be in the United States.
"We didn't want to do it in U.S. because we didn't want it to feel like every other wedding," Hannah shared. "We have waited all of these years, and I think for us, it was like, 'Let's make kind of a fun experience with it and make it a little bit more intimate.'"
Dylan added, "I think we're also super private, relatively. Doing it outside the States helps us with that, and we love traveling in general."
Dylan also advised their followers not to get married in Los Angeles because it would cost about $75,000 for just the venue. He called that price "ridiculous."
And Hannah believes a destination wedding -- at their self-declared "insane" venue -- makes sense for her family that will be attending.
"For my family coming from Alabama to California, that's already such a far flight. So if they go a far flight, I want them to have a really fun, vacation experience -- if we can make it happen," the model reasoned. "So I think that's what we're doing!"
But besides the wedding date and location, Dylan and Hannah confirmed they don't have anything else locked down.
The couple, however, has already made their Save the Dates, which is on track with their six-month wedding-planning timeline.
"We're getting married [this summer]... A lot of the plans are up in the air, but we're going to chit-chat, really casual, through some of the stuff we're thinking about doing," Hannah said.

When it comes to their priorities, Dylan said he wants "good cocktails" -- including Espresso martinis and tequila -- cigars and "good music," not old wedding classics like "The Cha Cha Slide" or "Shout!"
"I want it to be very elegant, classic, and timeless, nothing trendy," Dylan explained.
And Hannah said she wants the whole event to be "fun" while she stays present and "in the moment." She'd like to blend in, hang out with loved ones, and not feel like "the host" of a party.
In terms of how many guests they'll be inviting, Hannah said, "We wanted to keep it pretty intimate. I don't want to leave out anybody, but we wanted to keep it pretty small."
Dylan chimed in, saying, "I think around 100 or 120 will go. There are specific locations, that if we had the wedding there, it would have been a 400-person wedding."
Hannah and Dylan said they won't be splurging thousands of dollars on a wedding cake and so they're not even sure if they're going to have one.
"I can just make a cake right now for 30 bucks," Dylan joked.
They are, however, open to doing a first look, and they're also considering writing their own vows and reading them to each other in private.
"I don't really want to do them in front of people," Dylan noted. "But I'm open."
"I go back and forth [on that]," Hannah said. "I really can't decide."
In addition, Hannah and Dylan are thinking of having a formal black-tie affair in which the guests will have to adhere to a certain color palette of maybe three or four shades.
"I don't want to see women in orange gowns," Dylan admitted.
Hannah and Dylan will also have an outfit change during the evening, with Dylan sporting more than one jacket.
And Hannah boasted of the wedding gown she has yet to select, "I have style! I've got taste! Let's go!"
Hair, makeup, photography, videography, and much more has yet to be determined, but Dylan said he's been working on the food.
As for what's next, Hannah and Dylan will be celebrating their bachelor and bachelorette parties in June. And they've begun discussing their honeymoon, possibly the Maldives, Greece, St. Tropez, or maybe even a trip to Asia.
For several years, Hannah and Dylan were in no rush to get married after their Bachelor in Paradise engagement.
In fact, the pair revealed last year that they had decided to postpone their wedding in order to cut back on spending since they had just bought a new home together in San Diego in late 2021.
Hannah and Dylan have also been traveling the world together in recent years, including a recent vacation to Paris, France.
In February 2022, Hannah checked in with her followers to answer their burning questions, and one person chose to ask about her dream wedding dress.
"Part of me wants simple, but then I'm like... I can always wear a simple dress. You know? Maybe I go big, like Vogue. I don't really know," Hannah told the fan.
Hannah and Dylan initially decided on an early 2020 wedding, but their planning got derailed due to the global outbreak of coronavirus -- and now more than three years have passed.
"[The date has been] pushed back a bit. We've been eyeing 2023 so we'll see how it goes," Hannah told Us Weekly in September 2021.
Dylan said at the time he and Hannah hoped to wed in Spring 2023 because they don't want to exchange vows in the winter, and Hannah shared how they had already hired a wedding planner and anticipated tying the knot in California since the West Coast has captured their hearts.
"We're loving being engaged," Hannah gushed to the magazine in 2021. "We are excited to, like, start the next chapter whenever that is though. We are getting eager for it."
During Bachelor in Paradise's sixth season, Dylan called Hannah the love of his life and said he had no doubts in his mind that she was his person.
Dylan basically fell in love with Hannah during the first week of Paradise, but Hannah was a little terrified of investing her heart so quickly into a man following her breakup with Colton.
Dylan, however, never gave up on their potential, even when Blake Horstmann was trying to charm Hannah and steal her away.
After Hannah worked through "a few obstacles" inside of herself, she and Dylan got engaged on the beach in Mexico.
During the reunion portion of Bachelor in Paradise's sixth season, Dylan said popping the question to Hannah was "the best decision" he had ever made.
"We talk all the time, like, 'How did this all work out for us?' But for some reason, it did. He's my person and I have a different kind of love for him that I knew existed, and that's really special," Hannah shared in Summer 2019.
Hannah also revealed at the time they had met each other's families and she'd be moving from Birmingham, AL, to California in order to be closer to Dylan and his job.
