Have your first Belikin or Rum Punch at Jet's Bar while waiting for the hopper flight to AC. Jet is a character. lol
Eat a meal at Elvi's...I think it's a must do for 1st timers. Great food!
Pack light...fancy clothes aren't needed nor are many pair of shoes. Get out of the hurry, hurry syndrome...time seems to stand still on the island. Talk with the locals. They are charming people.
You will have a wonderful time & I can hardly wait to hear about your trip.
