As soon as we have our international flight numbers to/from BZE we let the hotel know and they make the Maya or Tropic reservations and send us the confirmation number. We have used both airlines and don't have a preference.
One reminder, tho....make sure to have your name and where you are staying in all of your bags. Last year one of my carry-ons didn't arrive in San Pedro with me and I was told that that at the end of the day, all of the "left-over" luggage would come to San Pedro and be delivered to the hotels. They were right! Armando was at our door with it around 7 that evening. Since it was a carry on, I didn't have all of the hotel info in it like I did my checked luggage so they had to search for a delivery clue. They found a folder in a side pocket with emails from the hotel. All's well that ends well!!
We are going in February, also...189 days to go!!
