Not sure there is much to be excited about. Sure if I had plans to stay between now and April (Already have a booking in early Feb) I would take advantage of it but I wouldn't make any changes to my plans or anything near like a mattress run as these are only reward points. Remember these do not count towards membership renewal anymore.
So unless the I am practically staying at a hotel and earning the same as I am spending (Even then I would wonder why I would do this) it does not appeal to me.
