I'm about to order my tickets but just need to ask a quick question. My mother isn't sure whether she will be coming to the water parks with us or not so can't decide whether she needs the options added on.

If she gets a base ticket without the options but then decided to join us at Typhoom Lagoon would she be able to use one of the days on her base ticket or do they not accept those at the water parks? I wouldn't want her to have to pay at the gate[msnscared]
