Sounds wonderful! Isnt the water warm and beautiful? Went to Maui about 12 years ago - free trip - had never even considered going there before.... it was awesome - the snorkeling, the warm water, windsurfing, the volcano, the fish nibbling on you right off the shore, the beautiful views (even if its raining) - going on day cruises, we were literally still jetskiing two hours before the plane took off!
Have a wonderful time - and enjoy yourself streached out on that warm sand and thinking of all of suckers here on the "mainland!"
Have a safe trip home!
