The T/Agent could get us the same R/C Cruise you found on VTG but was £100 dearer and no onboard credit which was $75, are you sure its a safe site as just been on the chat room and was advised to be wary as a lady on there booked with an internet site that went bust and she only got her money back because Tompson honoured it at the time, (they dont now as they changed their policy)!!
That was probably a UK agent, For both my bookings with BestPriceCruises the CC has been charged by the CruiseLine and was on the cruise line booking system soon after, I thing V2G may work the same way. But they have been around for ages and do loads fo busines, I get recomendations from US people that use V2G as well.
