I'm a Disney vet, but meeting both sets of grandparents (my sons grandparents) there for the first time (well, the first time in many years, anyway). I've booked them all on ME from the airport and am working on EXPLICIT instructions for them from airplane to parks, essentially. Grandma #1 - arriving incredibly early. She'll ME to POFQ, leave her carry on and head to DTD to meet friends. Should she try to check in at 9 am when she gets there knowing that the room won't be ready? (We've requested close or connecting rooms so I'm figuring if they know that early it might stand a better chance of happening - also forgoing online check in for this reason - agree or disagree?) Grandparents #2 - arriving noonish the next day (we may possibly be at the parks). ME to POFQ before check-in time. They can pick up their KTTW cards so they can get into the parks, right? Then will they have to "check-in" again later? Is there anything about Disney check-in, ME, getting to the resort that you find confusing that I should tell them about? Any problems you've had that I should warn them of? (They are all planners themselves but have left this up to me, so if something is iffy I suspect them to have some serious issues with me, which I'm trying to avoid).
