The first thing we need to know is if the hotel WANTS us to come help, which must also take into consideration if they have the building supplies to get the work started. If Castle Comfort doesn't have any remaining hotel rooms or useable dive gear, would anyone else on the island? They need tourism to help their economy!
If we can't get this work trip confirmed on the calendar by the end of 2017, then it will be time to change plans for the May 2018 dates.
