Better check what the cancellation policy is now. For Dapper Day they want a non-refundable one night deposit for the GCH.
If you are planning on Sept 19 - 23, GCH still have Dapper Day rates available. You could get the room for $249 a night.
Someone in your party needs to attend/participate in Dapper Days to be eligible for the rate. You also need to stay the night before or of the event, so no, arriving on the 19th wouldn't work. You have to book through Dapper Days to get their rate.how do you book with dapper day pricing? thank you.
I plugged in the 19 - 23 on the actual Dapper Day website and it allows you to make the booking.
As far as I'm aware, Disney aren't asking each guest if they are actually attending any Dapper Day activities.
