I wanted to put my own 2 cents into the conversation:

Bob and I met Ngaire and Ken ( and Linda and Ron) during the Voyager Baltic cruise which she escorted last year. Her attention to detail in organizing excursions for our group made our experience in Russia very enjoyable. In addition, it was a lot of fun to socialize with them. They are very down to earth.
I thought it said a lot about Ngaire that when she found out I was having sleepless nights because the vibration problems in my cabin, she offered us the spare stateroon in her suite!Talk about going beyod the call of duty! We didn't take her up on the offer ( eventhough they extended the invitation more than once), but I was very impressed with her thoughtfulness.
