I just called MS and they have no record of anything scheduled. They offered to call over and check with the resort which I appreciated. The resort (OKW) reported to MS that they have nothing on their schedule at this time for April.
It would be fairly unusual foir a resort to close it's main pool during Spring Break month. This type of maintenance is usually reserved for Jan-Feb time periods. I could understand an unexpected outage, but a scheduled maintenance cycle would not make sense.
Lets hope this is just a rumor and until confirmed should not be considered credible.
