Just back from a 4/5 star AI in Egypt. It was ace!
I'm an early riser, so would usually be on a sunbed by 0630 but on this holiday I sat, book in hand, on our spacious balcony until 8. DH and I then casually wandered to the Lobby Bar for a decent coffee, then into breakfast and finally out to the pool by about 9 where there were always lots of beds and shades available.
DD would get up at about 10 and get a cold breakfast from the pool bar (pastries/sandwiches etc) before joining in with the activities.
Around midday/1pm we would either get a snack from the pool bar open from 12pm to 4pm (burgers, chips, panini's, pizza, chicken kebabs) or go to one of the 3 buffet restaurants open 12pm to 2pm where you could have hot/cold/soups/salads/pasta etc.
In the evening we had the choice of one of 2 buffet restaurants open from 6pm to 9pm or one of 3 a la carte restaurants open from 7pm to 10pm. There was also the option (not that we ever did it) of 'midnight soup' from the Lobby Bar.
Oh, there was also a beach bar that served snack food from 10am to 4pm
Never saw any of the issues listed, never had any sickness and were very impressed with the hygiene shown in all areas.
Didn't cost the earth either - less than 4K for 3 adults, 2 weeks (DD is only 14 but unfortunately still has to pay an adult charge).
If anyone is thinking of going to Egypt I heartily recommend the Jaz chain and the Sunrise chain. Last year we went Sunrise and had pretty much the same experience except there were 7 a la carte's, so we didn't use the buffet restaurants at all. Slightly more expensive, but still some good deals to be had.
