Las Vegas offers dozens of shows and attractions. Purchasing tickets online is both efficient and wise. At the time of pick-up, you need to present a photo ID and the credit card used to reserve the tickets. This ensures that your tickets are not given to anyone else, and that your credit card is not lost or stolen. If your tickets can be printed from your computer, you may not be required to show identification when you present them for the event, but it is best to have your photo ID and credit card with you just in case.
Most hotels in Las Vegas require photo ID and a major credit card to reserve a room. The photo ID gives them the security of knowing who their guests are. Reserving the room rate on the credit card provides them with assurance of payment by blocking out that amount on your credit limit. When you check out, it is likely that the hotel will allow you to pay in cash or with a debit card instead of charging your credit card. In this case, the amount that was held on your credit card for the room reservation will be released back to your credit limit.
The ability to cash checks in a Las Vegas casino can be critical for guests. Most ATMs impose a withdrawal limit, as do most debit cards. For large cash withdrawals, check cashing is often the only option. To protect you, the person writing the check (if it is a 3rd party) and the casino cashing the check, photo ID and a major credit card are required. Be prepared to pay a fee for this service.
