The A/C is on during the day, if some of the downstairs ones aren't on (if it's too quiet in the bar) they'll turn them on if you ask. Klaus is the manager during the day, very easygoing guy. Quite helpful if you need any advice or directions for the island.
Oh... and if you consider yourself a sharp player one of the bartenders will inevitably try to have a game with you. He's a local champ and has some mad skills at 8 ball. Be forewarned...
