20日倫敦 + 法 + 意 行程 ~~ 請幫忙!!! (10點)

1. Unless you have friends in London, 5 days is too much. Of course if you are also going to Scotland and Wales. This is even a little rush.
2. Paris - should be suitable
3. Sorry for this question.
4. I suggest you to cut Marseille, (all you can see is sea and seafood of course), save 2 days for Switzerland. In fact, you cannot stay in Venice for 3 days unless you are a painter who likes to paint arch bridges and canal. Therefore up to now you will have 3 spare days, which should be enough for a trip to Switzerland. Also the routing is even smoother this way. For Switzerland you can choose to stay in Luzern / Interlaken, or use Luzern as a base and stay only one night at Interlaken. Visit the Swiss Tourist web site and you may change your mind to have more time in Switzerland.
5. Not sure about where to buy coach. But Eurostar is not a good choice. Just normal train inside an underwater tunnel. The procedures and timing spent are more than travelling via coach.

in day 5, you might wanna stay a night in tunbridge wells, because then it will be quite close to the port where the eurostar, the train, are, or you can also take boat, there. eurostar, is quite nice, because it is a under sea train, I heard it got quite a good view.

補充一下, coach應該是指euroline吧, 上網找一下, 不過要坐一整晚(約九小時)還要落車上船, 價錢也與eurostar差不多(除非你好早訂)

五天在倫敦是多了點, 省下兩三天不如放在羅馬

七月中是歐洲人旅遊高峰期, 早d訂hotel之類呀
