For me, life is short. I wouldn't put up with a fiance trying to take anything away I enjoyed. That will only be the tip of the iceberg....it will get worse when they're married.
Now, I WOULD ask where he wanted to go, and make it happen. We normally take 3 to 7 trips a year, two are 1-week vacations and the others are weekends, so there's plenty of opportunity to see and do other things.
I did most of my world travels when I was younger. Very fun, but A LOT of WORK. I like WDW now because we have
DVC and it's a whole family vacation. We take our time, cook great meals, invite our friends over. We spend about 6 nights at Disney then 3-5 nights elsewhere in the state.
