I posted all the following information in a CM-only thread, but I thought I'd repost it all here incase anyone else needed any clarification.
We ask that no more than parties of 6 be seated in our Special Needs sections. We do make exceptions for parties of up to 9, depending on how early the party arrives for seating. Parties of 10 or more must separate due to the limited seating. If you are able to transfer (and willing), please let a host/hostess know, it makes seating so much easier. If you require seating with a back support, we have VERY limited seating in the Maleficent and Sebastian sections, or we also have the option of giving you a wheelchair to sit in, if you do not already have one.
Special Needs seating is available in all 10 sections of the Hollywood Hills Amphitheater, with parties of 2 (ONLY 2) and parties needing reflective captioning (No more than 4, please) seated in the Mickey section.
Yes, there is seating directly next to the guest in the wheelchair/
ECV. Only one person from their party may be seated in that seat, with the rest of the party seated on the designated benches directly infront of the guest in the wheelchair/ECV.
The exception to that, however, is if you are seated at either end of the section, since the 2 end benches can hold up to 4 people. And, yes, there is an exception to this rule as well: The Mickey section (remember, only for parties of 2 and parties of up to 4 requiring reflective captioning)
This is all true for each section, except for the Pocahontas section. There is no seating in this section directly next to the guest in a wheelchair/ECV. Guests seated in this section are seated as follows: The guest in the wheelchair/ECV is seated at the top, while the rest of the party is seated in the rows directly infront of the guest travelling in the wheelchair/ECV.
**Edit: Btw, we really don't recommend you charging your personal ECV in the outlets that are in the theater. Power spikes do happen, and the possibility that your ECV could be ruined exists, and Disney is NOT responsible for such a situation. We recommend you charging it at Darkroom, Oscar's or GR. Obviously, if it's a Disney ECV going bad, we have the ability to replace it.
Hope that clears everything up
