I just returned from escorting a group of 16 onboard the Jewel of the Seas' 12 night Scandanavia/Russia itinerary and must say that overall, this was an excellent cruise.
Flights- I negotiated a group airfare with Delta for the group who departed from Tampa with a stopover in JFK in both directions. The group said the service onboard was wonderful and the flights were all on time. I was flying from Seattle and flew United in order to arrive before the group in London. United upgraded me to Business Class and they lie-flat beds made for a very restful and pleasant flight.
Upon arrival at Heathrow airport, we were shocked not to encounter any lines at Immigration and Customs and were outside boarding our private bus to the hotel in about 20 mins after landing.
