All depends what you want out of it and where you want to go
Alot of Disney theme parks tend to be fat friendly but alot of places like NYC are also fat friendly!
Also Miami beach if you wanna stay in the USA
If you wanna visit Europe I recommend Ibiza, Magaluf or anywhere lit and lively!
I’m suprised by Miami Beach, which I think of as way too fashionable and Hispanic to be very fat friendly. ( in my experience, Hispanic women in S Florida and PR are very sensitive about weight.)
