Just adding this to the conversation probably without a lot of value, but after all these years I am considering getting 4 day one park per day tickets instead of a 3 day parkhopper. Its $15 LESS for 4 day vs. 3 day parkhopper from the DL website. Last time we were there we only hopped one of the three days and it would have been nice to have an extra 1/2 day on the first of last day of our trip. And they both come with a magic morning. I decided not to do Orbitz or LMTC in case something happens with our dates (there are five of us, and flexibility is valuable peace-of-mind). I get 5-6% cashback with my credit cards, so sometimes I buy Disney gift cards and purchase tickets with them... sometimes I get great gas station rewards tacked on. I wish Costco would offer tickets again, really.
I guess I could always upgrade my tickets to parkhoppers once I was there if we found it necessary... I think I can upgrade to three or four day parkhoppers from four day, single park tickets because they cost more.
