I voted the 22nd-28th since we'll be there on all those days, but we're actually leaving WI on the 18th and driving down over the course of 2 days. So technically we'll be in WDW from the 20th-28th, but our official vacation starts the 18th - 29th.
We're staying at All-Stars Sports ... DS' 6th birthday is on 8/6, and our 10th anniversary is on 9/30, so this trip is part annual vacation/part birthday celebration/part anniversary celebration.
