My partner and I stayed in the Royal Decameron Issil on the 6th - 13th July 2013 and we had a lovely time.
We were fully prepared for the language barrier from reading the reviews on trip advisor, but as we both know a teeny bit of French we got on ok.
When we arrived we had a warm welcome and drink from the Hotel staff and were shown to our room which was probably the furthest away from the main complex. We were actually offered a room by the pool a few days in by the Reception staff which we thought was a lovely gesture, but we politely declined as it was actually quite nice to have a distance from the disco etc at night as it could get a tad noisy.
We did a couple of trips while we were there, we didn't have a problem finding a travel rep as the Receptionist at the hotel gave us a British tour company details as soon as we arrived. We did the half day in Marrakech (more than enough, especially in 44 degree heat!!) and also an authentic meal in a Moroccan restaurant. We felt we were bumped on the restaurant trip as it cost a lot of money for what it was, and the hotel actually did a better Moroccan night food wise anyway!
Food wise, I had a bit of tummy trouble but my partner was fine, could have partly down to the heat as even our Rep said when we were over there they were having a bit of a heatwave! There were a couple of moody waitresses in the Restaurant who really didn't seem like they wanted to be there but I managed to get one of them to crack a smile at me eventually!
The entertainment was something to be desired, it usually began with a mini disco in the main lobby from 9 - 10 (with the same music in the same order each day!!) then the crowd would move onto the Theatre for about an hours performance, then onwards to the disco until 1 am. We tagged along one night to see what it was all about but it wasn't to our taste shall I say!
I don't have any real negatives to report really, we didn't feel any hostility from the people in the hotel or in Marrakech itself, but we could have been lucky. Whilst we were on our trip in Marrakech a lady on the trip accidently took a picture of one of the 'water men' and he came up to her demanding money. It's a shame but actually a lot of places in the world are like this, accidently snap a picture of pretty much any locals and they will be demanding your cash!!
Would we return to this place, probably not, probably not because our attitude is that there are so many places in the world to explore, why keep going back to the same place?
All in all I would recommend this place to fellow travellers, maybe not those who want a 'British' oriented holiday as you just won't get it here.
