Hi Heather, Ocean City is great during the off season. There's still so much to do and lots of places open. You'd be surprised at the number of people on the board walk and walking the beach. The name of the hotel is the Clarion Resort Fontainebleau Hotel. The only way to afford a place like this (for us anyway) is during the off season. It's still a bit pricey for off season, but Thanksgiving week is our families vacation week so we plan to spend for it. It was $99 per night plus $25 per night (non-refundable) pet fee. They probably do have a dog # limit but I think two is ok. I saw one man with three little dogs on leash in the lobby.
The Fenwick Inn (another nice hotel) allows pets and they are 1/2 the price of the Clarion but we really wanted ocean front. The Fenwick Inn also refunds the dog deposit (I think), the Clarion doesnt.

The Clarion had a spa to die for! Steam Room, Sauna, Eucalyptus Room, Hot Tub, Tanning Beds, State of the art exercise equipment, etc. We spent every late afternoon sipping drinks pool side while the kids played in the pool. The Clarion has two resturants, two bars and a night club with live top 40 music. The Fenwick Inn also has an indoor pool and a very nice penthouse resturant.
We were going to go to Asateek (sp) Island to see the wild ponies on Sunday but it was so cold we went to the mall instead. I will shut up now.

Here's the web site.
