Keep in mind that there is no electricity and the resorts that have generators are having trouble getting diesel fuel so they may not have electricity for long. There is no diesel available on the Island from what I hear.
When will power be restored.......anyone's guess at this time. I'm not in Belize right now but many friends are keeping me informed. I would guess that gasoline is also not available but I don't know that for sure. That would mean your mode of transportation will be a bike or walking. Can't charge electric carts.
Hopefully recovery will not take too long. So much property damage along the windward shore to docks and structures over the water. I'm so sorry for your losses. I wouldn't advise any tourist to travel there for the next few days until a clearer picture of the damage and recovery is formed but that is just my opinion. Big mess to clean up.
Thinking of you.
