How to surprise the wife??

[BrandonGetz]

we are coming down in September and we have always stayed at Riverside, I told my we couldn’t get in there this year and are at Coronado Springs, but truthfully I booked Beach Club(one of her top two all time resorts she wished to stay at) but she has no idea since I do all the booking. Now the problem lyes in how I tell her? I want to wait till day of arrival and that. Trying to get some opinions or ideas would be greatly appreciated!
