fboy i went both sat and sun. the lines were not bad until about 10:30 or 11:00 am on saturday. first thing in the park at 9:00 and you have free run until about 10:00. hulk took till 10:45 to get to 75 minute. The water rides were really stacked due to the hot weather.
Sunday was great, the lines did not start until about 10:30 again. It is amazing how few people there are at the gate at 8:30 am on sat and sun. again the water rides stacked due to heat.
