請問怎樣旅遊便宜

你是指每次只遊一個國家還是一次過遊多個國家呢

如果是每次只遊一個國家
當然是pacakge會比散買酒店+機票抵

如果是一次過遊多個國家
你可以考慮選擇用airpass / budget airline

[airpass]
你可以考慮star alliance或one world既airpass
應該啱你用
Star Alliance Circle Asia Fare

Star Alliance Asian Airpass

另外，one world寰宇一家亦都有隻類似既airpass
Travel Round Asia and Australasia with oneworld Circle Fares

詳情你可以上返li兩間公司既website，或者去返旅行社問
建議你去返d大agent
或者去學聯問下
因為li類product未必間間旅行社都有做

[budget airline]
air asia 是兩間比較大的budget airline
主飛東南亞

For Singapore, Malaysia and 吳哥 . You can buy a package tour that means airticket including hotel ( that kind of package) it is cheaper.

But for 印尼 越南 I so suggest you join a tour package with any of the HK tour company.That is because of safetly reason
