December vacation ideas somewhere warm with low chance of food poisoning

I (38F) have 1-2 weeks off in late Nov/early December to travel - either with my husband (38M) or solo. We are traveling from Seattle and we are hoping to go somewhere warm. We talked about going to Bali in the past but unfortunately, these days I've been dealing with a lot of gut health problems and couldn't risk getting traveler's diarrhea. It sounds like "Bali Belly" is pretty common so we are ruling that out for now. Alternatively, do people have advice on how to have a nice fat travel experience in places like Bali and avoid food poisoning? We aren't tied to Bali but it has the combo of being warm, good food and it's a place we've never been.

We haven't been to Europe in a while but it seems like a bad time to go weather-wise. We'd love any ideas, particularly if it's easy to get to from Seattle and it's safe for women to travel solo. Thanks!

Edit: Thanks for the responses everyone! Love a lot of the places mentioned below. We've been to Hawaii, Costa Rica, Mexico, Japan and Australia in the past few years and loved those places but we're interested in seeing some new places. We've also talked about Malaysia / Morocco / Turkey / Azores / Beijing (I know it won't be warm but it's been on our list) - curious if those places are pretty safe food-wise?
