We found it difficult to locate any reviews of La Marguerite cruises prior to our cruise, so hope this will help future travellers. This was our first river cruise and was mid-November from Siem Reap to Saigon.
Although you can book travel to/from embarkation/disembarkation and can also book add-on packages, we chose to make our own travel arrangements. We flew to Siem Reap from Bangkok, easily obtained visas at the entry airport and stayed 3 nights in Siem Reap visiting many temples and seeing the local sights - this is not to be missed. Most cruisers had already done associated tours of varying lengths and stayed at Le Meridien in Siem Reap but we stayed at a really good small hotel called Pavillon d'Orient where the local staff were really friendly and helpful.
There was some confusion for us about exactly where we would embark and neither AMA Waterways nor Fred Olsen Travel (the UK Agents) distinguished themselves in this regard. Apparently, just after the rainy season and for a couple of months thereafter, embarkation takes place on the Tonle Sap Lake about 20 mins drive from Le Meridien. At other times there is not enough water in the lake and you have to be bussed to a more distant embarkation point downstream which can be up to 5 hours away. We received several letters from AMA/FOT advising us of a change of departure point and time but never one with the actual ones. It was left to us to discover this in Siem Reap!
Good quiet mid-hallway cabin. Just as good as those (more expensive) on the deck above
