Some notes...

Travelling in Paris
beware of pickpockets
buy entrance tickets online to avoid long queue, e.g. Eiffel Tower
check out some museums (i'll look for free entrance, hehe)
pay a day visit to Marseille
be alert to Gypsies approaching you

A 2/3 days detour to Belgium?
chocolate and mussels strongly recommended

Italy
beware of pickpockets etc.
too many places to visit (why not save it for the next trip?)
definitely pick Rome if you insist to visit Italy :)
be careful on your belongings (repeat) (sounds like the country is not too safe ehh?)

London
a  must: Phantom of The Opera
another must: Full English Breakfast (errrrmm, is there a not so meaty one?)

before my memory fades, i need to jot it down here. it's about time to plan my route and make arrangements!

See you in March next year!
