We've always stayed at Ixchel so I'm not sure about the beach clubs there. The ones around that hotel seemed fine. I'd think it would be hard to go wrong.
I've felt safe on the streets there at night. I'm typically not out super late but walking back after a dinner (9:00pmish) never felt unsafe.
Tarzan's is great for drinks/snacks but they don't have a huge area for umbrellas and beach chairs. We really like Green Demon for their drinks and food. They also have a nice setup with umbrellas and lounging "beach beds". It also not so crowded/congested in that area.
The streets are definitely safe to walk at night. Especially the "downtown" area on Hildago. We go all over the island at night though and never feel unsafe.
Feel free to text me if you'd like. I can also recommend lots of other places. (903)875- nine 3 Juan too
We really like Kin Ha on the south side of the island. Rope swing, kids slide and paddle boards and a few other activities. Been there twice and enjoyed it both times.
