I know this is a bit of an old thread; I found it from a Google search.
I'm an owner at AR and I can tell everyone that they have definitely updated their units. They've replaced the tables and kitchens with marble surfaces and new appliances, the floors with new ceramic tile, and the master bedroom beds with king-sized beds. The master bathrooms are still a bit dated-looking, but they are spacious, clean, and bright.
I recently got a second week at AR on eBay at a really great price. You'll find them now and then from people/brokers who just want to unload before the next year's maintenence fee. But AR's dedicated resale broker told me the other day that resales are averaging around $5500, and have not gone below $4500 in recent memory.
AR has excellent management and a unique location, which keeps its value up. When places like Los Abrigados are struggling financially (rumor has it), AR actually has a reserve fund of like $800,000.
What I hear and see is that AR's weekly value is down from the normal $8000 area, to around $5500 since the economy changed. eBay just lets some people get lucky sometimes.
