All of you have given me valuable information and interesting opinions.
I was not actually asking for parenting advice, BUT I know ALL of us parents can't help but give advice to each other. It's in our blood!!!!
I did put the tough-love idea into consideration. Force my son onto rides. Chances are...he'd end up liking some of them. Maybe even love some of them.
But I have changed my mind. I thought about how I'd feel if I was going on a vacation and I knew I'd be forced to do things I was afraid of. I don't think I'd have a good time. I think I'd be constantly nervous. I'd constantly have butterflies in my stomach. It wouldn't be a vacation. It would be one big anxiety attack.
I think one of the most wonderful experiences I have with my very fearful son is when he decides ON HIS OWN that he's brave enough to try something new. For example, when he was around 2 years old, he suddenly decided he wasn't terrified of escalators anymore. We rode the airport escalator about 10 times. To the point that I became nauseated! But I was so proud of him.
I love Disney World and have been there SO many times. But I can take or leave the rides by now. I'm actually sort of bored by most of them. I think what will make them fun is when my child IS interested in going on them. And to see the rides through his eyes. But I think this will be more pleasurable if this is his choice. Not something forced upon him.
I did push him to go on one ride. That was It's a Small World. I knew there'd be nothing scary on that. I also knew he'd find it entertaining. He has always been into Geography.
There's not really any ride or attraction that I know he'll either a) not be afraid of b) find it interesting/entertaining. Nemo seemed the most likely because he has seen the movie and likes it. So, that is why I asked the question.
Anyway, as for the parks being worth it without going on rides. Not really!!! So although we take long trips to Disney World, we're planning to do only 1-2 park days. Until he's brave enough to go on a lot of rides, hug characters, watch shows, etc. Then we'll buy the annual pass and go every single day of our trip!
Not sure when that will be. Maybe when he's 6. Maybe when he's 10. Maybe he's 17. Yes, it's weird to be 17 and terrified of The Winnie the Pooh ride. But we all have something weird about us. And in the scheme of themes...a phobia of Disney World rides is really not that important.
