The ship is quite something. I saw other ships in port next to us and I was glad to be on the Epic. The Aqua Park is wonderful. The slides are great, kids sprinkler area is too cute. So many hot tubs you always found a seat. I think one large pool would have been nicer, but not really a complaint.
My kids loved the Recess and wanted to attend most nights, which was a pleasant surprise for us.
The Nick characters are not out and about, which was a little disappointing. I know its hot, so I thought they may show up in the Recess area at times, but didn't. The best time to see them was at the character breakfast. They did schedule some events, but they were usually late in the day while in port. This made it a little tricky to attend b/c the kids were usually exhausted.
I thought the room was more than adequate. I don't have anything to compare it to.
Rounded bed, which our feet did hang off, but I didn't put much thought into it.
Shower and bathroom area are big enough. I am a large woman and felt like there was plenty of room in these areas.
Tons and tons of storage, we didn't even use it all. Two huge closets. Three large drawers. Two storage cabinets under counter.
Our room had bunk beds for the kids. One in ceiling and the other the couch. All fit just fine, absolutely no complaints.
