A few months ago, my immediate family decided to go back to WDW. We suggested to MIL and FIL that they should go too. We pay for ourselves, they pay for themselves. I told MIL to sign up for disney emails/ the DVD and that she might get discounts. She got a pin code for the free dining plan! They booked a room and we used their discount to book a room for us and some friends (3 rooms total, the max for one code). We are traveling in October. Tonight she calls me and tells me they changed their reservation and that they are leaving 3 days early. I got upset because 1. she didn't tell me beforehand and I tell her EVERYTHING I do / change/ idea I have about the trip and 2. I was (am) afraid that since we are on her reservation we all have to travel on the same time. The discussion got very heated between her and DH (I don't know why) and she said she was going to cancel. If she cancels or changes her reservation does it affect ours? One of our reservations is paid in full, the other isn't. Does that make a difference? THANK YOU FOR READING!! AND I APPRECIATE THE ADVICE ANYONE CAN GIVE!!
