Our visit to Weezies and Botanical Paradise was fantastic. The small cabins basically have their own pools (or are shared with another). They are arranged in a little neighborhood that leads to a dock with plenty of seating and swimming at the end. At the entrance to the dock there is a great trail that goes around the airport and different neighborhood spots that we rode bikes on for awhile. Bikes were available and we took them into town although it's possible to walk too.
Our cabin was the perfect size for 2 people. AC worked great. Water pressure was good. We walked to the local market and got groceries and made breakfast every day in the kitchen.
The location is not in the town center so if you're looking for something more quiet but walkable/bikeable to town, this is the spot. Micheal the host was great and very helpful. The people who live on Caye Caulker are very friendly and the vibe was laid back.
Re: covid- Caye Caulker and Belize in general were much more conservative than parts of the US. Wearing a mask outside is mandatory and people will tell you to put it on, even if you are walking down a road alone. That's not a complaint, just making people aware! It was easy to get the required Covid test to get back into the US and Belize accepts your vaccine card to get in. It was the perfect first vacation after a year of quarantine!
