The GF has some honeymoon rooms that are octagonal in shape and have jacuzzi tubs and AMAZING castle views. These rooms are in the main building and will be considered Royal Palm Club concierge. Check out the GF faq for more on concierge. There are also suites here, in the main building and in some of the lodge buildings. I think Conch Key has suites that can have one, two or three bedrooms. I know California Dreaming has TONS of info on the GF faq. Please check it out.
The Boardwalk Inn garden suites are two stories with private entrances. They seem absolutely charming and romantic and I hope to stay in one someday.
There is a one bedroom suite at the Polynesian. Check out Tikiman's site. You can even send a private message to Tikiman and he'd be able to answer any spepcific questions.
WL junior suites are great deals. There are only 4 of these in the hotel, but each has a king bed and a jacuzzi tub. Very romantic.
There are suites at YC and BC, but I don't know specifics on these.
There are also suites at Coronado Springs Resort, which is the only moderate that has suites.
I think the Contemporary has suites, but I would think they aren't as romantic as the GF's honeymoon rooms.
Animal Kingdom has suites but I don't know the specifics.
Someday I will do what you're doing and surprise DH with a weekend trip in a romantic resort. Have a great time!!!!!!!!
