Guest Services cannot ask for evidence of your disability due to the Americans with Disabilities Act, they have to take you at your word.

They don't give a DAS Card for named conditions, instead they will ask you why you are unable to queue as usual. So talk about your symptoms and how queueing in the heat will affect them, stress that it will severely curtail your visit otherwise.

Ask for a pass on your first visit for the duration of your stay otherwise you may have to ask at each park you visit which will significantly eat into your time.

When you go to guest services all members of your party will need to be with you so they can be added to the pass as well. They will usually add up to 6 members of your party to the pass.

Hope this helps.

Good luck with your Merlin trip.
