I've rented directly from an owner at Bonnet Creek Resort in the past. It was an AMAZING trip. Bonnet Creek is essentially onsite (location wise), and you could watch the MK fireworks from the balcony. They have a full water complex with a lazy river, mini-put, beach volleyball, etc. The only thing missing at the time was plentiful onsite dining, but we had a car rental at the time so no problem.
That being said .. Here are the negatives:
- you had to have a car (they have transit to parks but I think it goes to the TTC and was once an hour)
- no magic express from airport
- parking $$ at WDW
- difficult splitting up
- there is something about having someone make your bed that feels like vacation ;
I didn't mind staying onsite last time. However, it wasn't all that magical, and the room standards cannot compare to off property (and I was staying Deluxe). What I did like was being able to take my DDs to the park on my own, while my DH was taxied for free to the golf courses. It was always easy to meet up. For that reason alone -- the ease of doing our own thing -- we are staying Disney this time. But, we are getting a car rental half way through our trip on points so that we can eat offsite. Not doing the dining plan thing, just booked a room-only with a 40% discount.
If you need info on the owner -- many others have used him after me -- let me know.
Also, I used Undercovertourist for our tickets. I posted the costs on another thread. Check out Mousesavers.com for doing Disney on the cheap. ;
Edited to add: The 2-bedroom, 2-bath condo with full granite kitchen, dining room, and pull-out leather sofa in the living room was $120 nightin April 2008 ... beat that Disney!
