Recs? Group in their 30s, September 2026

Hello! I’m looking for recommendations for some all-inclusive packages under $1000 for 3 or 4 nights with airfare in mid-September 2026 (likely 9/16 - 9/19). This is for a group of friends (4-8 people) in their 30s. Can be anywhere, but I have already been to Cancun - willing to go back, but other suggestions would be appreciated! Adults-only would be nice, but not a dealbreaker.

I’ve used cheapcaribbean in the past with no issues, but I’ve been hearing some bad reviews recently so I’m reconsidering it.
