I think Suzie has the right message - if it's a good marriage different tastes in holiday's shouldn't matter too much.
I agree with other posters that it's worth checking what exactly is bothering him so much - does he feel unappreciated? I really hope it's a storm in a teacup and you all end up having a great time.
My experience is much closer to Maggiemay sadly - my soon to be ex had completely different interests in holidays - he was a fishing and sailing kind of guy - which I was fine with, and I would go along and make the best of it. Sadly I wasn't "allowed" to like different things to him, and Disney holiday's were not an option except for one short visit when he wouldn't come with me (but put me down endlessly and gave me a very very hard time when I went anyway). Once I am free I am going to have the best Disney trip of my life!
