Yet another ticket question (or two)!

[K&A mom]

We'll be visiting DL the end of April and though I originally purchased 3-day PH tickets, we now will be visiting for 4 days. I know that I can add a day to the ticket at the park, but want to confirm the best way to do this. At WDW we were told to use tickets at least once before adding days in order to get a better price on the added day(s). Is this also true for DL, or do you have to pay the gate price for additional days no matter what? Also, our first day in the park is 4-29, which is also the last day for the adult-for-child priced tickets. My sister and her kids are going with us, but they've had a flight change and now may not make it in time to use their tickets that day (they've already purchased them). What would be the best way to handle this? Thanks for your help!

How did you purchase the tickets? If you have E-tickets it might be worth seeing if you can get a refund and re-purchase the correct tickets, so you don't end up paying gate prices (online price is an extra $12, but gate prices is $50 more)

I'm not sure what to tell you about your sister's tickets. April 30 seems to be a black hole between ticket promos. The kids price promo ends April 29, but the 2 extra days promo begins May 1.
