Hi Carolyn,
Congratulations on your upcoming trip and happy (almost) birthday to you and your hubby! I would check with your husband's doctor to be safe, but I suspect that he will be able to ride a number of attractions throughout all of the parks. At the Magic Kingdom, for example, rides like: It's a Small World, The Many Adventures of Winnie the Pooh and Peter Pan are very slow moving and easy to board and exit. At Epcot, Spaceship Earth, Nemo, and most of the countries (with the exception of Norway, which can get bumpy) are slow moving. At Hollywood Studios, The Great Movie Ride and all of the shows are a good choice, and finally, at Animal Kingdom, many of the exploration trails are designed to explore at your own pace and should be fine. Again, these are just some of my suggestions, and PLEASE do check with your husband's doctor to clarify what his limitations are.
In addition, if your husband has difficulty walking for prolonged periods, you may want to consider renting either an Electric Convenience Vehicle (ECV), which is like a motorized scooter or a wheelchair. Both are available for rent at each of the main theme parks. Click

Finally, click
HERE for information on Disney's disability site for specific information that I may have omitted.
I hope you both have a magical Disney birthday!
