There have been a number of threads, with an even larger number of posts relating to the 'Water Police' and the bag searches and (threatened)confiscation of bottled water at certain hotels. What I am curious about is are the hotels taking the same attitude towards drinks bought in the Duty Free shops.
If you buy your limit of DF alcohol from the UK DF shop - 1L of Spirit or, I think, a box of wine it is perfectly legal to take it into the country. You then get the opportunity in the next 48hrs to buy up to another 3L of Spirits in Luxor. (Not to mention anything else that you can buy at one of the local shops if you so choose). That's a fair amount of alcohol - 4L Spririt - that could conceiveably be taken in to a hotel on check in alone, and fairly obvious for all to view.
Are the reps on package deals warning people in advance of any of these problems so that guests can be aware?
Whilst I do have certain sympathies with businesses trying to keep things 'in house', I can see that as most visitors to Luxor hotels are only on B&B basis that more and more will start renting flats and doing self catering!
