I hope they still have them beyond April 8th. I think they will, and it's just that they're slowly putting the times out. Just a few days ago, I'm pretty sure they only went up to March 31st with the times, and the next time I looked they went up through the 8th. So hopefully within the next couple days or weeks they'll extend it out again.
I wouldn't put anything past them at this point, but it would be kind of silly to get rid of them before the conclusion of Spring Break season, the Galactic Nights event, and Dark Side half marathon weekend.
