I wonder if anyone can advise us regarding suitable clothing/footwear and anything else we need to be aware of on our forthcoming Nile cruise? We will have some early morning starts and we would like to know how cold it is likely to be at 6.30 am when we go off the boat? Will we need long sleeved tops and trousers? Are sandals OK or are trainers better for sightseeing round temples? We are back on the boat for lunch every day and then relaxing for the afternoons.We have been on beach holidays in Egypt before at this time of year but we were never up that early!!
