You will probably be able to get on as it should be in a soft opening phase in March. The press event (official opening) is April 7th, but prior to any new attractions official opening they will have it open through the day for guest to ride so that the cast can get ready and they can work out the last minute kinks. A soft opening means that it may or may not be open, it may be open for a few hours in the day it may not open at all. They will not announce that it is open, it is just kind of a right place right time thing so you have to keep your eyes open for it. Basically it is a test and adjust phase which gives them an opportunity to open for a few hours a day to get people on it but they are not obligated to be open or stay open.
