When you say your communications from the Spanish site, are you referring to the fact that every time you go online to the RCCL website, it comes up with the Spanish site? If so, that's an easy fix. Simply wipe out the cookies and history from your browser, and begin again. Then when you go to the Welcome to Royal Caribbean International

But it's funny how the prices can vary. We have several clients in England and sometimes they find our prices better and other times they find their prices are better. Just depends on the specials being offered and the exchange rate between the pound and the dollar. Same holds true with the euro. So you may find it worthwhile to get a quote from both a Spanish agent, English agent, and a U.S. agent to see what works best for you.
