You've pretty much done the nicest route, and it's kinda similar to my last trip. I would probably head back, if I had the chance, through Madagascar, up through the safer parts of Africa (you'll need to do alot of research on safe places. Get the most recent Lonely Planet World on a Shoestring book), then up through Morocco, into Portugal, across the top of Spain into San Sebastian, then race through France(not a big fan) back home.
I would love to do that trip…

Hello Phil C,

My name is Phil D

I didn't make that up. It just sorta happened that way.

Now let me be serious my friend. There is a prefered site for frequent travelers such as yourself.

It is the Gulliver's World Travel Data Bank Service. You may consider it a gift from me to you.

I have used them many times with great success.

Go to the referenced site listed below:

I think the cheapest home route would be through Thailand. Choose from a wide variety of popular airlines and budget flights.

You should have passed by the Philippines if you like the beach, Boracay in Aklan is just an hour away from Manila (by plane).
