True or false?

I am a young lady intending to travel next year to Europe and go backpacking around Europe. I love to shop whenever I arrive at a new place & I just can’t help but buy. If I am traveling alot I’ll have to carry less baggage with me so please help me plan my trip. Your contributions are much appreciated. Thanks all.

Hello Everyone! My girlfriend wants to travel to Brazil next year for carnival, and would like to use a travel agent to plan our arrangements, while I would much rather plan everything on my own using the internet as a primary resource. Could anyone tell me the benefits and negative aspects of using a travel agent to plan a vacation of this type? Also, I would really appreciate it if anyone who recently traveled to Rio De Janiero could share some opinions and perhaps “insider” tips on traveling to this destination. Thank you.

Like best dining, dress code, customs, safety, best time to travel. My parents are thinking of going and would like to start planning their trip.
