Now, about the fireworks dessert parties:
We have done them at MK, Epcot and Hollywood Studios (I keep waiting for ROL at AK to get a Dessert Party LOL) at one time or another, all within the last 5 years.
Personally, I think they are worth it, simply because you get a special experience for a fairly reasonable (in the Disney World economy) price. We never eat as many desserts as we think we will, although they are typically quite good with a nice selection.
I will say that MK fireworks dessert party was for me a bit more difficult the last time I was there, simply because it was easy to kind of get overrun when the fireworks start, although I understand from someone who has done one fairly recently that has been addressed by Disney by changing the layout of the tables, so I am looking forward to going on our next trip.
Do make sure that her doctors (cardiologist and primary care) are on board with the trip. Be sure to have her insurance card with you, in the event she needs medical attention, and make sure that at least one other person besides her is up to date on her medications, dosages and timing.
If you are flying, you can bring a wheelchair from home, and it will fly free as medical equipment, and can be gate-checked; she can ride all the way to the door of the plane. Many airports are *huge*, and the wheelchair will mean that someone she knows is pushing her.
If you are driving, and renting the wheelchair in Orlando, then try to rent a lightweight chair; a mesh back if possible (air circulation for greater comfort) and regardless, bring along a pair of bike gloves or golf gloves (can be purchased for very little at
Walmart) to help prevent blisters if the rental chair has the old school, hard plastic hand grips. Sweaty hands + black plastic, hot from the Florida sun = blisters. I know from personal experience!
If you all are staying on site at a Disney Resort, she can remain seated in the wheelchair, and the driver will flip out a ramp for the chair to go up/down. Mobility devices always load first, unload last, on all Disney Buses and boats. The Monorail is the exception, but a Cast Member will have a portable ramp to bridge the gap. Any time you are unsure where to go with the wheelchair, just ask a CM (Cast Member) for help.
Let us know if you have any other questions!
