Many major hotel chains, including Marriott and Sheraton, charge for high-speed Internet access in your hotel room. Fees start at about $10 to $15 per day. To avoid these charges, ask if free Wi-Fi is available in common areas, such as the lobby. Also, ask the front desk or concierge if there are restaurants that offer free Wi-Fi nearby.
If you have a smartphone with a data plan, you can skip the hotel Internet altogether and just use your phone to surf the Web.
