Your voucher is valid from 1st November– 30th April 2020. This experience is available Monday–Thursday (excluding Valentine’s Day, Mother’s Day, Father’s Day, Easter Weekend, bank holiday Mondays, Christmas and New Year’s Day). Please book at your earliest convenience to avoid disappointment. Boarding commences at 3.15pm at Tower Pier; the boat leaves at 3.30pm and returns to Tower Pier at 5pm. Seating is pre-allocated before the cruise takes place; your voucher entitles you to a standard seat on board. Window seats can be requested at the time of booking but are not guaranteed. Most of the tables are located in the middle of the floor space and in very close proximity to each other, with each table (or pair of tables) seating four people. Aisles separate them from the window tables, which seat two people only. The boat must keep to a strict timetable and so latecomers will be unable to board the vessel. All dates are subject to availability.
