I just received this offer in the mails and find it to be a good deal considering that you get 5 days at their studio villa which normally sells for $299 per day. You also get 7K SPG points which I value at the minimum at ~3 cents a point (thus $210 in value) and $185 for Avis Car Rental. Thus your total for 5 days at this fabulous resort in Kaanapali, Maui comes to under $400.
It is a great resort for families with kids as they have lots of activities for them plus a wonderful beach in front. Maui has been one of my favorite destinations ever since I visited the islands several years ago.
