Hi there, we haven’t stayed in the Oasis Hotel before, however i know its near to the Pyramids and would only cost you 1 pound starling by taxi to get there from the hotel.

you should also visit khan el khalely, its great to go there around the evening time, smoke shesha on one of the cofe shops( even if you are not a smoker its fun to do).
Becareful crossing the streets, may be get your husband (I am assuming he speaks Arabic) to agree a price with a taxi driver to spend all day with you taking you to all the diffrent places. 200 Egyptian pounds for the day should be fair. if your husband is Tunisian he should get cheaper entrance fee to most of the sites .
go by the nile and get on one of the fullucas, sailing down the nile is not to be missed.
shopkeepers will hassle you to buy from them, remember you don’t have to buy anything, after all they are very friendly people
all the best and have great time. it will be fun. ahmed
