Hi John, Welcome, and Aloha to you,Yes, stress is a factor in IBS. It can make you worse, but stess doesn't cause IBS.There are lots of motels/hotels very near to Disneyland. I assume you are going to the Anaheim park and not Florida.There are also lots of restrooms there. The best bet is to stay near the park and get there as early as you can, right when it opens. That way you can get on some of the more popular rides before they get crowded. One of the secrets of visiting Disneyland is to take the train first and then get off at Adventureland/frontier land. Then you can see the haunted house, and Pirates of the Carribean, both not to be missed, then you can go over to the adventureland cruise which is close by. Get those over early and then you won't have to stand in line too long. I know there are new rides that are exciting also in that area. Can you afford a two day pass? Maybe it would be easier on you if you can visit on two days instead of one.There are plenty of places to get things to eat there and quiet areas where you can rest. Go slowly and rest often. I don't mean to write a book, but I used to live near Disneyland and we had it down to a science. But be prepared for crowds, however.Don't get too stressed over it, you are going to have a good time.Can you smuggle me back in your suitcase? I haven't been to Hawaii in many years.
