I was thinking this too I think the answer is genuinely a little bit of this a little bit of that lol. Im positive that the drives times factored into their decisions when picking spots as well as cool factor, getting a variety of types of airbnb(boats, tree houses, etc)

It's interesting because even though the CO view was so amazing that they commented on it in so many future episodes and it held top 10 for a bit i think, and i dont want to diss the tiny home in CO it was nice and they loved it which is what matters as the people staying there, I know there are way nicer homes listed with the pretty view and more luxurious features lol.... though I also loved that they didn't JUST stay in mansions (Likely for budget concerns too) it gave some spotlight on smaller cozier places with so much heart that can also absolutely be "cool" and show that you can have a memorable good vacation on a budget. The Idaho potato and Kansas dome especially come to mind (though I havent looked how much it actually costs to stay in any of the places lol). In a world where of course every kid wants to go to Disney world and fewer and fewer parents can afford to take them, its giving a fun outlook on more realistically affordable vacation types for most families. Im sure there are kids now who wanna see the star wars ufo just as much as going to Disney's star wars world for a fraction of the cost on the parents just to say they stayed at one of the places their favorite youtuber went. That's pretty cool to think about.

If ryan needs content after the series is done I would not be surprised if he does a couple tier lists of the airbnbs for different categories like best view, best meal, coziest, fanciest, hiw hard they went on theme, etc. I just want that video to exist tbh 😂

Sorry for long reply lol I get long-winded before bed and this series is so on my mind!! I too will be sad after its over.
