Hi Goofyfordisney,
I believe all the club floor rooms are the same standard size. It's larger than most standard hotel rooms. It was larger than the room we had at Grand Floridian. There were five of us in the room.
We had a rollaway bed brought in. When it was down for the night, it was a bit cramped and we had to climb over the beds but when it was up for the day we found we had enough room to feel comfortable. There are two queen beds, two very comfy armchairs with ottoman and lots of counter and drawer space. The bathroom is split up into a water closet with bath/shower, toilet and small sink. Then there is a vanity area with another sink and large counter area. This arrangement worked well for 5 people getting ready in the morning.
Our room was at a great location at the end of the hall. Very private and quiet. We did not encounter any maid service problem. By the time we came back from the parks around noon, the room was completely clean and comfy. At around 6pm, they'd return to turn down the beds. They often placed the kids' stuffed animals in cute configurations to surprise them. They also laid out the robes and left a goodnight favour. Not the usual chocolate but distinctive souveniors like hard rock magnets, keychains, etc.
Towels were also changed twice daily. We had a great poolview. I could see the entire pool and slide and vollyball area. I could keep track of my kids during the afternoon from the room.
My kids are 13, 10 and 9 year old boys. They were at Disney 7 years ago. The 2 younger ones don't remember much from that trip. They absolutely loved Universal and IOA and Citywalk. They also loved the Hard Rock and the pool. They all met kids their own age especially the 13 year old when he sort of "crashed " a birthday party with 9 girls his own age. The atmosphere was a lot of fun. We spent every afternoon at the pool and every night after touring. We were there for four nights and wished we stayed longer. The best thing of all was the front of the line perk. Nothing can beat that. We were let in without any wait whatsoever, all walk ons. You can imagine how special your kids will feel when they walk past huge lines of people to board the next ride.
So it was a huge letdown to go to Disney after that. I think it would have been better for us to go to the Poly. We went to Ohana's for dinner one night and the minute we walked in the lobby the atmosphere was different. My 9 year old noticed immediately and asked why we didn't stay there instead. Perhaps you can go to Disney first then Universal. That way you won't feel the let down. We met many people at the club lounge who warned us of it. All agreed that the HardRock/Universal experience was much more fun and more value for the money. The only thing my kids liked at Disney were the water parks (very crowded), Test Track, Rock and Roll Coaster, A Bug's Life and the character meals. All the other rides were lame and boring even to the 9 year old. Hope this helps.
