EVERYONE needs a visa into Egypt. I assume you are traveling on a Canadian passport? If so, you can

I am looking at booking flights for my trip this summer. I want to fly from Edmonton to Mombasa, then I will fly from Nairobi to Cairo (or somewhere else in egypt) and then from Cairo back to edmonton. Just for the Edmonton-mombasa, mombasa-cairo, cairo-edmonton car rentals vancouver canada it is looking like $6000 when I check expedia. This seems way too high. anyone have other ideas?
As Atravelynn says, use Kayak to check prices. You might price out Edmonton - Nairobi - Cairo - Edmonton separately from Nairobi - Mombasa - Nairobi. Fly 540 Airlines in Kenya has some good fares on that route, so you might want a separate ticket for that.
What we have done in the past is to check sky scanner, see what routes they offer and the pricing, then try the actual airlines directly and see if there is a price difference. That way you can save time searching as they give you all of the airline alternatives and you can either book with skyscanner or with the airline directly.
The train doesn't go anywhere near the Serengeti which is in Tanzania. As stated, the train travels only from Mombasa to Nairobi. The train also ONLY travels alternate nights, 12/hrs. and often delayed. Departs car rentals vancouver canada 7pm with supposed arrival 7am next day either direction.
EVERYONE needs a visa into Egypt. car rentals vancouver canada I assume you are traveling on a Canadian passport? If so, you can buy your visa at the airport for $15 USD - have USD on you, and best to have proper change if you can. If you are not a Canadian citizen, then you should check with the Egyptian Embassy in your country to see what the rules are, or you might post your nationality here and see if we are aware.
Good point pody22, but can you clarify if this ONLY applies to fully legal wives, or does the Orfy wife get in without a visa too? I bring that subject up as MANY foreigners may not even be aware that they are Orfy wives or what that means, and if they show up without a visa or expecting to buy a visa, they might be surprised.
