I know you are SO EXCITED!!
My son and his family are going next week also and it is their first trip as a family. (My son visited with our family as a child, but DIL has never been.) I have been so busy helping them plan, get ADRs, etc., that I haven't even started my pre-trippie for our June trip! They are now getting really excited, and I am almost as excited for them as I am for myself!! I can't wait to hear how everything goes for them. I have been sending them all my collected tips, packing lists, recommendations, etc.!
As far as your mom is concerned, I hope everything works out. We always go with my daughter and her family, and we learned on our first trip together that the family just cannot stay together all the time and have a happy trip.
Everyone needs to understand that in advance.
My daughter and I are early to late commando types, but my SIL and husband need down time. Teenagers want to sleep late, pre-schoolers need naps and rest, early-birds want to hit rope drop, etc. With cell phones that is so much easier these days, so I hope that helps y'all have a good time together.
I love Pop! We stayed in the 70's just past the elevator, and it was a great location. It was an easy walk to everything. The bus stops are on that end of the main building, and that might be closer to the 80's, but we just went through the building anyway.
We are planning to stop on the way when we go (May 29) so I will be interested in hearing where you end up. I have a coupon book (from the visitor center) with all those discounts, so we may just see how far we can go since those are all walk-in coupons. We will need a couple of rooms so will want to economize.
Hope you have a wonderful trip in every way. I will be looking forward to hearing more.
