I think that a person's behavior depends more on education than on nationality. I would not be afraid of our tourists at the hotel. You never guess who will be your neighbor by the pool or at the restaurant table. And the noisy companies of Germans or Poles can also spoil your holiday.
Yes, there are hotels that are very popular with noisy youth or from marginal tourists. Such hotels are not only in Egypt. For example, some areas of Mallorca in the summer are filled with English students. Sleep there you just can not. Agency managers are well aware of places and "unpleasant" periods in each country. And give you a full consultation.
