OMG, we are 21 days from our trip!
With 3 kids at POR the only place they can put you is Alligator Bayou. The other rooms only sleep 4.
We just stayed at Riverside in the arcadian house, and there was a laundry facility close by at the pool.
I can't remember......Are you driving? I brought along my own detergent. I can remember the single pack was at least a $1. If you can I would bring a small box with you.....I would say do laundry just so you don't have to carry so much with you. It is also nice to come home with at least some clean laundry. :)
We are flying actuall.....but I also was thinking of mailing down a package prior to our arrival with various things...maybe I can find a few travel size Tide detergent packs
