The staff at Six Star cruises are very helpful - once you actually get them. My own experience is, that they were struggling to cope with the number of callers, I did not get called back when I was told I would be, it took ages to get an agent on the phone in the first place, and I then (after paying what the agent requested as a deposit) got an email the next day, demanding the balance as it was overdue! This is not what I expect from Six Star, I've booked with them before, and not had this hassle. The girls whom I spoke to however were very helpful and got my cruise booked.
