Memorial Day weekend 1978.
5 days/4 nites at the Golf Resort Hotel, later renamed Disney Inn and then sold to military and renamed Shades of Green.
Spent 2 days in MK (only park there was) and 1 day at Sea World. Wasn't much else to do back then. Also visited the other 2 Disney hotels and the Lake Buena Vista village (now Downtown Disney Marketplace).
Lots has changed since then, some for the better, some not.
