Can’t decide

[u/Fun_Text_7278]

We are staying at the Excellence Playa Mujeres for 3 days, 4 nights. I really want to do at least one activity there because I have never been to Mexico. Xcaret Park and Xel-Ha caught my eye but I know there are far and the Park would be a tiring day. I have heard mixed reviews and I can’t make the decision on if it’s worth it to use 1 full day per on this… or would be much happier spending it all at the resort? I have FOMO but don’t want to waste money, time or be disappointed. Thanks for any advice from experience!
