BTW, if you are DVC the break even bwtn Premium and regular APs is only 3 water park visits, or 2 plus DQ, or PI*2 plus water park plus DQ, you get the idea. Since getting ours in May, my sister and I have been to TL twice, DQ once, and PI 2 nights with the second time being to get out of the rain and we could because we had the pass already. We know we will have approx 30 more nights on property with these passes so they are soooo going to be worth it but we only got Grandma a regular AP. We didn't get the DVC discount on hers so it cost the same as our premiums and she doesn't do water parks or DisneyQuest. We are definitely taking her to PI to the Comedy Club and the Adventurer's Club when we take her again though. We will get the 50% PI admission with the DDE card for her.
In addition, since it seems to be the next question- yes, the DDE card is worth it. Even staying in villas, we eat approximately 1 meal a day in the parks or at a resort and the 4 of us paid for the card in 3 meals on the May- June trip. Yes, we do stuff like share due to the huge portion sizes but it was still definitely worth it. Since we are all adults, we like the pace and such of TS meals and with the exception of places without TS restaurants, that is where the DDE cards are valid.
