Reservations are strongly recommended, especially for sailings during peak season, holidays, and busy weekends. Popular lots — particularly covered spaces and walk-to-terminal options — sell out. Booking in advance also typically gets you a lower rate than paying at the gate. Most lots, including the official Port of Galveston lots, allow online reservations. Some private lots can also be booked over the phone.
Cancellation policies differ by operator. The official Port of Galveston lots allow cancellations up to 24 hours before your sailing date with no penalty. Several private lots require 48 hours notice for a full refund. After your departure date, refunds are generally not available. Review the cancellation terms before booking, especially if your cruise plans could change.
