Got a heads up from my dad

Seems like my sisters family has booked a trip to WDW, OK so whats the problem
My Dad thinks it is the same week I am going
There last trip was a basket case, when I found out last year they were going, since it was my niece & nephews 1st trip to WDW I tried to give them pointers, but I fell on deaf ears, they had the unofficial guide book and knew everything, so a few days before the trip when they wanted me to give them a plan, I gave them next to nothing
I've never read that guide, but it must not work, since I had to ask after there tales of the trip, So what DID you do
If what my Dad is telling me is in fact the right week, My sister is not giving up any info about it, but I know how she thinks, she would hit me with it a few days before the trip and try to collaborate with the Commandos, well the joke will be on her, since it's not going to happen, I would be able to get more done with 50lb weights on me ankles then with there turtle speed
I don't think it would be to hard to dodge them the whole trip, since I like to dig in deep into the parks
