Explorer of the Seas Casino

[elkay68]

It has been a few years since we sailed with Royal Caribbean. We like to visit the casino, however we do not like to carry cash. I do not want to pay the 5% fee to charge to room. I emailed Casino Royale and they said even if you play slots and charge to room you incur the service fee. Is this correct?
also I know in the past on other lines we have been able to purchase casino credits prior to the cruise but that does not seem to be an option. Just trying to plan.

Bring cash. Unless you're Prime level or above you'll pay the 5% if you charge to your room, including slots.

If you call you should be able to purchase onboard credit.
