With our guests from around the world we get asked about guide gratuities every day. Guide gratuities are not included in the tour price. We do not include a fixed price gratuity as we want to keep the tours affordable for as many guests as possible. Guide gratuities are completely at the discretion of the guest. We employ a great and diverse group of guides. They guide because it is a fun job and they get to meet people from all corners of the world. Similar to service businesses all over the United States, gratuities are a small part of the compensation the staff receives. If you choose to give your guide a gratuity, it would be much appreciated. Gratuities are included as part of the pre-paid cost for our private group tours and corporate events.
