We are staying at the Wyndham (Aura) in October. You might want to check out Orbitz or Expedia on better pricing. We are staying 12 days and got a price for everything for $1500 total for 2 people. Break out the $900 for air, and the it's less than $30/night per person. We've read good and bad reviews on the Wyndham, but my parents stayed there this spring and said everything was great, and they travel 3-4 times a year and only stay at AI's.
We chose not to use the dive shop on site and go with Dive with Martin (they will pick us up at the pier at the hotel, but SDS charges you $3/day to do so), after the smug & rude email replies that came from Sand Dollar when asking questions.
The differance in price per night is 3-4 beers...
