Total waste of money as far as we were concerned. My 17 year old daughter, her 18 year old boyfriend, as well as my 15 year old daughter were bored like I've never seen before at both US and IOA. It rained ALL day EVERY day we went. The wait times for the rides were 2+ hours. Express passes were gone by 10am, so they were useless. The rides at US were lame and in dire need of updating. Other than Spiderman and Hulk, the IOA park was lame as well. My kids said that the local Six Flags offered MUCH more than these two parks combined. We bought a 7 day pass and only went two days. Stayed manybe a total of 12 hours. Seen it all in that time several times over and had no desire to return. Staff members at the parks were rude and unhelpful. They seemed less interested in being there than we did. We decided to do an informal poll of folks and the comments we kept getting were that the parks were boring and the lines way too long. The only good thing about the parks were my daughters know to never take there kids there Seriously, we were VERY unimpressed with US/IOA. We ended up spending the rest of our vacation in the Tampa area. Now that was a good time at the beaches!
