Good news, my friends' place has electricity, and the carpets are drying out. Still has to replace sheetrock.
Went to the Schlitterbahn website and saw some encouraging news...
Clean-up at Schlitterbahn Beach Waterpark on South Padre Island in the aftermath of Hurricane Dolly is moving swiftly. "Due to our pre-storm preparations and the design of the park, Schlitterbahn Beach was fortunate to have received very little physical damage from Hurricane Dolly," according to general manager, Keith Fontenot. "It has mainly been a matter of clean-up and we will be ready to re-open soon after the power is restored," he added.
The park staff has drained and cleaned all of the rivers and pools, washed and wiped down all the surfaces, checked and double-checked all the rides and slides, and tidied up the park's tropical landscaping. Now it's a matter of waiting for full power to be restored. "Utility crews are working rapidly on the island and we expect to have our power on shortly."
