I had to find a good price hotel for another friend in Moab, so I thought I'd pass along what I found. Not a lot of hotels are available, most are booked solid. If you haven't made reservations this might help.

The Ramada is booked solid.
The Best Western has rooms available $75.60 regular/$71.10 both are plus tax (lower rate is with sr or AAA discounts). 1-800-780-7234.
Super 8 has rooms available. It's within walking distance to Portal. Even the lady I talked to said these rates don't make sense. Here it goes...
date rate
5/12 $52.88
5/13 $52.88
5/14 $55.88
5/15 $52.88
5/16 $65.88
5/17 $62.88
Super 8's reservation number is 1-800-800-8000 They to give 10% Sr. and AAA discounts.

Motel 6 offers available rooms (nearest hotel to Portal). Their rates are $75.99 per day plus tax.
