Thank you for posting this site i have have requested a quote for a cruise only from the UK,from them so far have had 5 quotes all from us ta all of them more expensive than UK ta very strange.
Not strange at all & hardly surprising as the dollar has been weak in Europe for some time & until it gains strength, which it is doing rapidly, the US agents have been struggling to compete with UK agents on European cruises. You will only benefit by booking a US/Caribbean type cruise, but as the dollar increases it's strength they too will be less attractive to UK/Europeans. One other word of warning, if you book a cruise now with a US agent & pay a deposit, by the time you get to final payment stage the Dollar could have gained so much strength that your final bill could be a shock to your budget. The only way to counter that of course is to strike a deal & pay in full before the Dollar increases further.
With an eye on holiday firms collapsing - in UK you can help yourself by choosing ABTA and ATOLL bonded agents - do you know if there is any similar protection (apart from using a credit card)if one books through US sites?
