I am trying to plan a beach vacation for later in the year (around September maybe) for my girlfriend and I, but I have never been to any of the islands and have no clue which one to pick. It would be for 8-9 days. Mainly looking for nice beaches with fun nightlife also as an option. I would prefer one that isn't still recovering from the hurricanes. Also, we enjoy areas that we can wander around and explore vs having to stay at one resort the whole time (we recently went to Isla Mujeres and really enjoyed being able to explore the island by golf cart and just stop in random restaurants/shops/bars etc). We would also prefer more of an adults only atmosphere vs being around lots of families and kids. Good food and cool bars for beach cocktails is always a plus as well. Budget isn't an issue, but not being ridiculously expensive would be nice. If anyone could offer some suggestions I'd really appreciate it as I have no clue where to even start. Thanks!
