Summarize:

Sight-seeing is a common practice for travelers. Think about the transportation, admittance and other costs related specifically to these trips. Most monuments, parks, and museums are free of charge but some may cost a small amount money. Research these sights beforehand so you can factor them into your budget. Look up pre-packaged sight-seeing tours in your destination. They may be the most cost-efficient and thorough way to see a locale's major sights. If you're planning on attending amusement parks, enjoying the local nightlife, or taking in a show, factor these costs into your budget. You may want to create a rough schedule of your daily entertainment plans so you can research them ahead of time. Use sites like Yelp and TripAdvisor to research local entertainment and get an idea of the costs ahead of time. Consider getting a AAA membership. They offer travel discounts at restaurants and entertainment venues. Many travelers purchase gifts for others other souvenirs for themselves. It will be difficult to determine the costs ahead of time so make a budget you can stick to. Make a list of the people you intend to purchase gifts for ahead of time and try to assign a rough dollar amount.
