You will get an automatic discount on your first tour when you book online at www.extranomical.com!

At this time only one discount code can be accepted per reservation. You must choose which one you would like to apply upon making your booking. There is a space for the discount code or “tracking code” on the final page of the booking form.

Not every code will be applicable to every single reservation. Please read the terms of the discount code you are attempting to use carefully, and note that some codes provided by third parties may have expired. If the code is valid and has been correctly applied you will see the value reflected on the final checkout page before submitting your reservation.

Unfortunately, any discount code you would like to use must be applied at the time of your booking. The code must be redeemed at the time of reservation and cannot be applied after you have made the booking.

Full refunds will be given for cancellations to any 1-day and half-day tour reservations made more than 24 hours before the scheduled departure time. Any cancellations with less than 24 hours notice will not be entitled to any refunds.

Tours with hotel packages and other third-party attractions tickets (ie. Monterey aquarium tickets) cancelled or changed with more than 10 days notice prior to departure, will incur a $35.00 fee or a fee of 10% of the package cost, whichever is greater.

Cancellations of any Tour package or 3rd party attraction ticket with less than 10 days notice will not be entitled to any refunds. Airport shuttles, Bay Cruises and Alcatraz tickets are nonrefundable.

You do not need to have a physical voucher to board Extranomical-operated tours.

If you have purchased the Ferry Bay Cruise tickets, your Expedition Leader will give these to you upon boarding your tour.

Please note that Alcatraz Cruises will require that each adult boarding the boat to Alcatraz bring their photo ID or passport for identity verification.
