Sorry if this has already been asked but 150 pages is a lot to sift through

...
Are YES classes available in June? Specifically, the second/third weeks of June? I know a LOT can change between now and then, but we're planning a second, extended-family vacation in 2016 and all of the kids will be old enough to do a YES program. Since most of them are on a tight budget, the current discount tickets are appealing.
OK, second question...
If I sign up DD10 and DD7 for the same class, I am only allowed to add either DH or myself. DH and I would both like to see the program so is it possible to do two separate registrations, one with DD10 and I and a second with DD7 and DH? It won't be an issue if the girls want to do different programs, but if they want the same one, DH and I would both like to go.
**OOPS! Found the answer to this one...no extra adults so this is a no-go.**
Final question...
If DH and I have AP's and the kids do not, we're basically screwed because we would still have to buy at least a 3-day ticket for one of us (the designated chaperone) correct? DH and I are going without the kids in November and we're planning a family trip next October. The kids would like to do a YES class but if DH and I buy AP's, we would still have to buy tickets in order to chaperone the kids at the YES class. Does anyone have any experience with this? Is there any way that AP holders can only pay for the class admission?
