"Dear Mr Kelvin,
It has now been a few days since we arrived back home after a nice tour / holiday in both Vietnam and Cambodia. Since we were not asked to fill in a feedback form for the last part of the tour, we still wanted to provide you with some feedback/observations. In general I must say that we have been very satisfied with the overall tour we have made. In general, the itinerary, the hotels and restaurants as well as the accompanying guides have provided us a very good level of satisfaction. I think we have expressed this in the feedback documents that were handed over to the tour guides in Vietnam. We were not asked to fill in a similar form after the Cambodian part of our vacation, but we feel it might be useful for you to receive our feedback / thoughts on this last part: All in all I would like to conclude by saying that we spent a lovely holiday in both Vietnam and Cambodia. We are also very pleased with the overall service that has been offered by your company. We really appreciated the flexible and solution-providing people that accompanied us on our trip. With this last feedback, we wanted to express our open and honest feeling of what will remain a very nice experience in our ‘travel memory".
