Vinny and JM added a couple of things I was going to, so I'll just add, don't underestimate the snack tray. I've looked at a couple other tubs, and they didn't have it and my wife strongly wants that. Its nice to have a place to easy get to a couple glasses of ice water to help us enjoy our tub longer.
The major hard part is over, May will be one of the longest months ever, and finally please let us know how it goes many people here will be happy to hear of your experience.
