I researched this extensively before our trip last October. We booked Portofino Bay at US/IOA for that reason. I had a lot of positive responses about the La Quintas and some of the other budget chains, but most of your nicer chains were downright snotty, even when they were lsited on sites as being pet friendly. The Residence Inns by Marriott sounded the nicest but they had a ridiculous fee. We had originally booked the Comfort Inn at US for our arrival night but got cold feet and just booked an extra night at the Portofino. You'll have a really pet friendly experience at HRH if it's anything like the PBH. Your pet gets his own goodie bag with treats, bowls, place mat, food can cover. Good luck. BTW, they definitely don't discriminate against any dogs, while we were there I took DDs to the pool and a lifeguard came to one of the tables and sat a bowl the size of a dishpan down on the ground. Coming behind her was a man with the largest GREAT DANE I have ever seen!
