My husband and I have around 40 countries in a list we would be more than happy to visit. While we do have a preference for what county is next we don’t let it be set in stone. We will look for prices on google flights if we have specific days in mind or wait for @faredrop to send us deals and we book our trips based around that. For example last year we really wanted to do a French wine trip then go to North Italy, but plane tickets where 1k each, but for the same dates to Bangkok it was $700 (where they usually are $1,400) so we went to asia instead. We are always grateful and happy where we end up and just love to be able to continue exploring the world
