Relax...
All Ears and WDWig.com (its sister-site) have a habit of reporting rehab rumors that turn out to be not true. Wait for Steve, moderator of this very site, to report it. Only then will it have actual validity.
My family was at WDW last Easter break and aslso during the week following (when crowds lightened up a bit). All Ears/WDWig.com said that Maelstrom would be down for rehab and it was not. And I was in a panic because despite two previous trips to Epcot, I hadn't been on the ride--1st time it was a month before ride opened to the public/2nd time was one of its first rehab periods. So alas, I was bummed that it was allegedly going to be closed again, only to be overjoyed that the rumor was false, false, false...
In fact, when we told CM's working Maelstrom about this rumor (while we were in line for the ride), they reacted like we were from Mars. Maelstrom did eventually go down for a short rehab in 2002, but it was much later in the year AND during off season.
I don't see how WDW can shut down one of the few rides at MGM during one of its busier times. Maybe sometime afterwards, but not during Spring and Easter break.
So again I say, wait for it to come from a reliable source like Steve before the moaning begins.
