I have now added my review. There is also another review by a young couple, staying at the hotel at the same time, whose experience was not as positive as my own.
Regarding sickness, I did have a bit of an upset tummy one day which I think was travellers' tummy rather than over indulgence (believe me, you can tell the difference!) so called the doctor via reception within a couple of hours of its onset as I had also been bitten and required an anti-histamine jab (suffered badly from infected bites in Hurghada in March). I was given medication and was subsequently confident to undertake a boat trip the next day. My friend suffered no problems but we did speak to another couple who had had a tummy upset too. This seems quite normal for many Egyptian hotels but not of my experience of either the Grand or Grand Resort. In 12 visits to Egypt I have only had one other day of discomfort, also coincidently in the height of summer. My husband, however, suffered very severe D & V at Hilton Sharks Bay 5 years ago and has not been back to Egypt since!
If anyone has any queries regarding either the Grand Hotel or Grand Resort don't hestitate to ask or pm me.
Only just over two weeks till I go back - yippee!
