Hi..

I'm planning to go to Macau from Shanghai and return to Shanghai again (SHANGHAI-MACAU-SHANGHAI 21dec-23dec'09 FOR 3PAX). Please advise me with these issues:

1.Which way is the cheapest way? Direct or via Shenzhen or via Guangzhou?
2.How can we reach macau from guangzhou? how much and travel duration?
3.One of my friends is holding Chinese Passport, do he need to apply any VISA? is Visa On Arrival available for him?

Thanks so much...
