We did it last November. They are very low pressure. spiceycat is right--ask for a rehab unit. We were in one of the old units and our bathroom was quite sad. Then, during the presentation we saw one of the new units and it was beautiful.
Driving back and forth to Disney was a hassle, though. Sea World is very close and we had a great time there (I have 2 DSs - 2&3).
