We just got back from DL yesterday, after a 6 day stay. On Tuesday morning we lined up early at 8:30am and were 2nd in line at the gates. We walked briskly to Nemo and waited about 20 minutes, but most of the time in line was spent walking thru the queue. We entered the park at 9:05 and were on the sub by 9:30. On Thursday night my niece wanted to ride it, so as we entered the queue it showed a wait time of 60 minutes but we were on the sub within 40 minutes. The time went by so quickly as we ate dinner in line and chatted with the family behind us. Not too bad. It's a cute ride, but I would not wait more than 1 hour for it.
