Overall, I would echo and agree with Dean's comments on Westin, Embassy and Marriott being the three that I would trade for on Maui. We are owners at Marriott Maui and actually just returned. I can't say enough good things about the property, however, it is hard to get in even for owners during the summer, but can be "had" during non peak times if you request a year in advance and are flexible with the unit size and timeframe. Summer is virtually impossible -the week we were there - July 23rd-30th, there were only 13 exchangers that were staying at the property and they were all Marriott owners from another property. Marriott has a 21 day priority period for Marriott owners who want to exchange in. To give you some perspective, there were over 2000 requests from Marriott owners for the month of July who wanted an exchange into the property. I was told that number really drops off after the August timeframe.
We have also stayed at the Embassy Resort Maui - it is a very nice resort and I would not hesitate to stay there again. In our most recent visit to Maui, we toured the Westin Maui and it is also a beautiful property, however, I also suspect it is similar to the Marriott in terms of trying to exchange into.
Good luck with your exchange
