We stayed in one of the 5 BRs several years ago. Really top notch, great beach, service, etc. We did pay as you go and spent about 1/2 what the AI cost was. I prefer to stay directly beachfront, unfortunately the 1BR is not. We got lucky and walked in and they gave us the 5 BR for 1/5 the price, it was just the two of us.
Since then, we've been staying in the Owner's villa at Nirvana, love the direct beachfront location. Not as luxurious as Moondance, but a much better value IMO.
