I just checked Expedia and your right there is condos for that price if you want to share accommodations with roaches. I don't want to book a place and then when I get there spend most of my vacation trying to find a better place to stay if there is one or find out everything was sold out. with DVC I know that it is a 5 star hotel and to book the same accommodation is 715.00 a night at the Aston Beach Tower
Ahh, many of those condos are gorgeous.
But even just a poolside garden 1BR at Aulani is 406 points for a week in the summer. Depending on your home resort ownership, that's $2900 to $3500 just in dues, or $400-$500 per day in just dues. (Putting aside the costs to actually purchase the points)
For under $300 per night, you can get this gorgeous penthouse:

For about $500 per night -- about the same as just paying dues for DVC / Aulani 1 BR stay, you can get this stunning 2 bedroom / 2 bath unit:



That's a heck of a lot nicer than an Aulani villa! I don't see any cockroaches.
Aulani does seem gorgeous. I look forward to hopefully spending a few nights. But I think it actually serves a pretty good example of DVC not really saving you money. Just pre-paying, so you get locked into the option. It certainly does seem like a really nice option, but if someone actually wanted to save money -- there are lots of ways to save far more in Hawaii, with absolutely amazing accommodations. Nicer accommodations for less money.
