I'm planning to travel to Europe with my girlfriend, i have few questions it will be our first travel abroad.
Above yun nakita ko na travel plan gusto ko lang sana malaman mga kailangan and mga hidden charges/
expenses dahil medyo malaki talaga yun kailangan.

Any symbian members here that can suggest or give tips na mga kakailanganin namin ng girlfriend ko to
travel in Europe (London, Paris, and Rome)

Thanks for your help!
