Need some destination ideas

My husband just told me we’ll be able to afford a vacation to somewhere warm next year and I’m already thinking about where we should go. Last year we went to Cancun on our honeymoon and had a great time but I’d like to go somewhere new. We’re open to all inclusive except we don’t drink alcohol at all so idk if it’s worth it. Some other things to note: We’d like to go somewhere either with no kids or maybe just very few kids there. We aren’t really nightlife people and my husband isn’t a big beach guy but he’d spend all day in a nice swimming pool if given the chance. We aren’t big on things like snorkeling or zip lining or anything like that. We had a couples massage at the resort on our honeymoon and my husband kind of hated it so spa-centric isn’t necessary. We do enjoy dining out, shopping for souvenirs and we especially like things like guided tours of historical and culturally significant sites. Our favorite excursion in Mexico was attending a night ceremony in the jungle where we were blessed by a shaman and experienced an authentic sweat lodge ceremony
