Hi!
Lucky you, I'm very jealous!
We went to Egypt last year and it was amazing.
We tried to cover as much as possible and went for two and half weeks, three days in Cairo, 5 day nile cruise and then down Sharm for the rest.
Stayed in the Reef Oasis Blue Bay and it was amazing! By far the best hotel I have ever stayed in, fab rooms, beech, food.
We did get vaccinations before we went, got them with the GP and cost abour €80 each. Can't fully remember what we got as some of them were two/three in one but your GP will advise. They last a few years as well.
Would advise considering going all inclusive solely for the alcoholic drinks! They can be very expensive, some of the five star hotels charge about €6 for a vodka/whiskey etc. Do plenty of research on your hotel and it will pay off also as I did hear some bad reviews on some all inclusive resorts.
Only went into Sharm twice, it's fine, very touristy depends on what you are into. Locals can be crazy pushy but we had gotten used to it, smile, say no thank you and they usually leave you alone.
If you have any questions let me know!
