I was really worried about the noise before staying in one of those suites for the first time last month. You definitely hear the sound of the freeway constantly 24 hours a day, and it did bother me a little. I found that I was tired enough that it wasn't all that difficult for me to fall asleep initially. The only problem for me is that I always wake up at least once during the night, and I found it difficult to fall back asleep with the traffic sounds. Freeway noise though wasn't as bad to me as street noise. We have been at the CCI in a room right out on Harbor, and that was really annoying. Despite the noise, the suite was totally worth it to us because we loved having the separate spaces and the two bathrooms, and I could definitely get enough sleep to get by. We will probably stay in the kids suite again if we get the entertainment/AP rate again.
