I am wanting to go to Ski Dubai and do the penguin encounter. I have the entertainer book which says it can be used for snowpark entrance (150 aed). However, the Power Pass (300 aed) includes the penguin encounter and park entrance, plus gloves, giant ball, mountain thriller, and chairlift. Is there a way to upgrade to the Power Pass and pay the difference plus the entertainer voucher? Otherwise the penguin encounter alone (150 aed) plus snowpark entrance (150 aed) is the same price and does not include all the other things.
