I called RC and verified that all the currency on the Voyager of the Seas for the Mediterrean cruise is still in US Dollars. I had read somewhere that it would be in Euros, but RC assured me it was USD! Just planning ahead for my gamling money!!
RC ships sailing from Southampton are now using Sterling as their on-board currency. This even includes all the gaming machines which have been converted for their time in Europe. Or at least we know this to be the case for the Legend of the Seas!
