You're welcome Tab We only stretched to Club Med once and were going to go to a 2 Trident one (their star rating) but ended up in a 3 Trident one as the one we were due to go to ended up not opening until later in the season. It was April last year and most sensible people were thinking of the Iraq war and not venturing to that part of the world - except us!!! So my view is probably a bit biased as we obviously ended up getting more than we paid for (even though we had already paid quite enough, thank you very much!)
We went to Palmiye in Turkey which is one of the larger Club Meds. Briefly in comparison to Mark Warner, the rooms were of a better standard, we had booked a family room which the travel agent (not Club Med direct) had said was 2 separate rooms with a connecting door. This turned out not to be the case when we got there and our family room was quite frankly horrible. (Something may have gotten lost in the change of resort?) We complained and because the hotel was quite empty we were moved to two separate but adjoining rooms which were clean, bright, nice bathrooms etc.
Food was great, a huge choice every day with various themes for dinner. It is much more international than Mark Warner, we met a lot of Dutch, French and Russians there. Although the staff would hotly dispute this, it IS very francophone but having lived in Belgium and speaking reasonable French we found this quite appealing. Of course, they do all speak English
We were happy-ish with the childcare - our kids were used to nursery and school at that stage but I think it could be a shock if your child has not done anything like that before. They also have loads of different nationalities in the kids club and all the instructions had to be repeated in about 4 languages. I don't know how they ever managed to get anywhere! It's worth bearing in mind that for the older kids (from about age 4?) the childcare workers don't have to have childcare qualifications.
We did have the feeling of being in a very upmarket Butlins at times which we didn't really feel in Mark Warner but we were comparing a smallish MW with a v-large CM.
Hope this helps, any other specific ?s just post.
