I just did this a week ago and we had a great time. Just be sure to check the height requirements ahead of time (online) double check their height at home (barefoot) before you go. See which rides you all can do together and maybe let them see some footage on YouTube. Let them know that we may not be able to do some of things we usually do. Now, I had my 11yo DS with me and when the other 2 did not or would not ride any of the rides I just walked him through the single rider line or through the normal line be sure he got on ok and waited for him In the child swap area. My girls started calling it the "line" ride. Just be open to the fact that you may only get to do the group or family rides but keep an open mind and finally get to see the whole parade and/or wait in line to see that extra character. Notice and read one of those signs you may have missed. Also, take more frequent potty breaks it was during our first park day I felt the pain of not having another adult to leave the other kids in line with while I take the "gotta go right now" kid even though we just went oh 5 minutes before we got into this line to the potty. BTW: my kids are 11,9, & 4. I hope you have a magical trip. ;0)
