Tara,
I wish I could break it down to just room rate for you, but we went through alaskaair.com for our vacation package. We watched for about a month and finally just booked in when we didn't think it would get any lower. We are staying there for 11 days for $1970ea. Most of my guests are paying $1300-1500 for the week, including airfare. I haven't had any guests book in under a week yet.
I tried to go through a TA but they weren't offering any better deals. I figured everyone could just book on their own and we don't have to worry about the headache of people not paying their deposit, etc.
I love the location. Mismaloya is further away from PV than I really wanted but it's so pretty. Love the jungle. I'm REALLY excited that they are upgrading the grounds too.
