The flight is only 9 hours and I am sure it will be ok. I have heard some bad reports about them in the past, but also heard some good ones.

When choosing a villa It is always best to choose one seperate from the package as you get to choose what facilities and location you get. Some have internet, some don't etc...

All the locations you mention are great and right in the heart of the action.

Hope you have a good time.
