Frankfurt's hotels tend to be very expensive, although some offer weekend discounts. During the numerous international trade fairs, many hotels impose surcharges and are frequently filled to capacity. Try to avoid Frankfurt at these times, unless you're attending the fairs. Advance reservations are always advisable. Excellent commuter-train service makes nearby cities such as Mainz and Wiesbaden very pleasant alternatives to staying in Frankfurt. Accommodations can be booked at the Hauptbahnhof tourist-information office for 3 euros. Open Monday-Friday 8 am-9 pm, Saturday and Sunday 9 am-6 pm.
