Looking for destination advice in the Caribbean Islands/Cancun area.
Important factors: Direct flight under 5 hours (only 3 day trip), nice but secluded beach area (couple is careful about tznius), water activities, good value, not too touristy, kosher products either available or can be brought in (not necessarily a restaurant), and other activities (i.e. rain forest/hiking, zip-lining or other).
Other advice: Resort stay or house/cottage rental, specific activities, and car rental or not.
Thanks in advance
