I booked a Thrill Waterpark cabana for our upcoming Harmony OTS cruise in May. However, only 3 out of 5 of us will be using the waterpark. Will the other two have to buy passes to the waterpark to access the cabana? Can the other two use the wave pool or do you have to have a waterpark pass for that as well? I can't find anything online and the RC representative I spoke with was not able to answer my question. Of course, I should have bought an Oasis lagoon cabana instead, but they are now sold out.
