Mickeefan,
No, you can't request which hotel you want for Priceline.
I bid on a 4* hotel/Disney area only/$55.00 per night (Not resort)
Priceline didn't accept that offer
I then added Universal area to my search and upped my bid to $60.00 per night
Priceline accepted that offer
Read
www.biddingfortravel.com, from reading this site I knew that there were no 4* hotels in the Universal area, so I was able to up my bid and still know I'd get a WDW area hotel.
I believe the 4* hotels are:
Hilton Downtown Disney
Wyndham Palace Downtown Disney
Swan
Dolphin
Marriott World Center
Read that website, it has alot of info about bididng, but remember, it's charged automatically, and is non refundable, non changeable!
Good Luck,
Leah
