I don't think it is a big deal to adapt to other people who have special diets or interests while traveling is a big deal or a sacrifice. In my younger years I met a group of girls at a hostel and ended up traveling together, I am a huge meat eater and one of the was vegan, so we ended up going to vegan places for the whole time and it wasnt a huge deal for me at all. I enjoyed the food, learned about new recipes, new ways of eating...
Another of the girls was huge on birdwatching, so we went birdwatching on a few ocasions and I really enjoyed it. IT wasnt something I would have done or something I might do again on my own initiative, but while there it was fun.
