It appears as the people that answer the questions on First Choice don't actually know what they are talking about. I had the same problems before we went.
The M/S Orchid is their AI boat and is totally dedicated to First Choice customers. The other boat either the Tulip or the Jasmine are for First Choice and
OTHER odds and s*ds from all over the globe. You will find that the majority of First Choice customers will also be on AI but all the others from around the globe will be on a FB basis. The problem with the scheduling of the cruise comes from having to wait for these other passengers. Also some are only doing the Luxor to Aswan bit and get off in Aswan. The Tulip or Jasmine is then stuck in Aswan waiting for more passengers to come on board for the Aswan to Luxor bit.
When I queried this with First Choice about the scheduling they said that on their web site it does state that changes in scheduling can occur. OK, fair enough, but that is only if it is due to unforseen circumstances. In this case it has become a regular occurance and should be pointed on in their brochures and on their web site.
The 'last morning' ,Monday, is advertised as being relaxing with the opportunity to do the balloon trip if you want to. On the Orchid that definitely is true
BUT on the Tulip and Jasmine it is
NOT. The last morning is gruelling. I have written about on this forum before.
As regards the standard of the boats the Orchid and Tulip-- I would say the Tulip definitely is better but that does not mean the Orchid is not good because it is a good boat. I would also say that food is more or less the same and, of course, the staff(except FC reps etc) will be fabulous on both.
As I have mentioned before. If you want to do things on that last day then it is vitally and crucially important that you find out exactly what boat you are on.
