I've worn mine for the last two or three trips and I get anywhere from 18k to over 30k. My highest day occurred when we started the day at Epcot at 8:00, hopped over to MK at 2:00pm and then stayed at MK until 3:00 in the morning. Unfortunately, since Fitbit starts over at 12:00am, I didn't actually get to record an over 30k day. Still fun to see the step rack up.
