joshman,
we went to altinkum last year,for the 1st time.our step son,flew out to meet us & stayed at the royal marina.i was really impressed,with the complex,so much so,we have booked to stay there ourselves,next year.
it is a very clean & well kept complex,with 2 pools.there is a little bar,which serves food as well.
it is a little walk,down to dolphin square,but we don't mind that.maybe 10 mins?
it is a relatively new complex,so don't think,you will have a problem,with your apartment.our step sons,was spot on,could not fault it,at all.
hope this helps
tracy
