The elevator system is really not that bad just FYI. a elevator usually comes in a reasonable time unless the lobby is super busy.
there is no charge for the skyride, ropes course. the trampoline park is in a different area of the ship and there is a charge i forget the exact price but i think it was somewhere around 7.00
I think it was in PV. where the Carnival ship docks there was a little shopping plaza and there is a sign that states Beach right outside with metal fencing. DONT goto that beach we walked about 30 min down that beach and there are zero services. It seems to be a beach only for the hotels and we couldnt even determine if we could just leave our towels on the sand and go in the water.
