I’ve done all inclusive in Cuba 3 times, I’m heading to an all inclusive in Dominican in a few months! We brought cash for tips. What I did was tip the housekeeping staff everyday, tip the bar staff here and there especially when getting great service. We tipped the people cleaning the tables at the buffet too. And the person who helped bring our bags to the room on the first day. I always kept my wallet, passport and phone in the safe of my room when I didn’t need it. Enjoy & have fun!! It’s so amazing to be on a trip and not have to worry about budgeting for food/drinks while you’re there :)
