Mahogany Hall is wonderful. It is truly beautiful, serene, and easy-going. I arrived on Sunday when there were families and locals at the river grilling, playing music, tubing, swimming, and more! It was nice to be a part of in the "backyard" of this stay.
This acted as the perfect setting for working/schooling while on vacation. The wifi only works in the common area near the bar FYI but was adequate for zoom, etc.
A true (yet quaint) resort, the prices are steep relative to general Belize prices. There is Big Tree Falls, a village about 20 minutes walk away that has a grocery store and some stops for food including Ricks, an expat spot with decent tostadas!
As for Vacasa, this was my third stay with them. They are an agency that is often remote from the local stay which means that they are only so helpful. I recommend asking around to locals or the Mahogany staff (who are incredibly kind and thoughtful) for tips on where to go or what to do. They offer their own concierge through whatsapp to order meals and ask question. Overall tremendous stay that I would highly recommend!
