We did the Nick Resort in the Fall and loved it. We got a really great deal with the kids getting free Sea World tickets with our Nick stay.
Loved everything about it! It is not something you spend 2 days doing. You need to spend sometime there to meet characters, see a show or 2 and play on the water slides. As long as you go there knowing it is not a vacation alone you will enjoy it. I thought the characters meets were fantastic. Zero wait and they took their time with the kids. We met Dora, Diego, Boots, Sponge Bob, Patrick, Squidward, Pablo and the TMNT during our 2 night stay. We saw the Double Dare show and the Dora Show. We had breakfast with the turtles. We had a suite with bunk beds for the kids. It was clean, roomy, well themed and we loved it. Don't be freaked out by all the bad recommendations.
