Hi there, Heather!
Thanks so much for stopping by the Disney Parks Moms Panel with a question for us. I'm more than happy to help. A birthday celebration at
Walt Disney World Resort sounds practically perfect, and I'm sure your children will have the best time ever!
As a single mom myself with three children, I can completely understand your concern. The good news is that there are plenty of
attractions where you can all four sit together. There are a few that you might be a little cramped, but you can probably put your youngest child on your lap and still fit comfortably. And since your boys are still little, they probably aren't tall enough yet to ride most of the attractions where you would need to be seated separately anyway. So as long as you avoid the attractions with height restrictions, I think you'll be just fine. If you have any concerns, just ask the Cast Member standing at the entrance. They'll definitely be able to tell you more about the seating for the attraction and whether or not you'll all be able to sit together.
I hope this helps to ease your mind a bit so you can enjoy your trip with your little birthday boys. Enjoy every minute of it and make lots of magical memories!
