I woke up around 4:30 EST, and checked for the heck of it, and was able to make a reservation for 12:50 on 22-April. It didn't immediately show up in on our MDE or an email, so I figured it was a glitch. My wife woke up before 6:00 and I told her what I did, and nothing was still showing up, and no email confirmation. My wife then tried, and was able to make a reservation on the same date, but at 2:30 which was the only time left available. A little after 8:30 my wife's reservation showed up in MDE and she got an email for it. Around an hour ago we finally got the confirmation on my initial request. Sounds like when the system is working, its lagging pretty badly.
