The price listed is the full price. No tax on top of this.
You do not have to go to the excursion desk at all. Your excursion tickets as well as information on the meeting place for the group will appear in your cabin by magic. Usually these are on the desk when you arrive at the stateroom for the first time.
Supposedly the cost of a
DCL excursion is all inclusive--any expected tipping was covered in the cost of the excursion. However, some bus drivers, etc. will have a tip jar out. This is totally optional. You are not expected to tip the DCL CM who will be with the group.
OK, from start to finish.
Book your excursion on line. You can cancel up to 3 days before boarding without penalty. IF you have booked on line, you don't need to do anything else re booking. The ticket will appear in your stateroom and the charge will appear on your onboard account. If for any reason the excursion is canceled (weather or whatever), the charge is automatically canceled--again, you don't have to do anything.
You will receive information in your stateroom as to what time and where your group will assemble. You will go with your ticket, KTTW, photo ID for over 18, and anything else you need (hat, water bottle, swimsuit, etc depending on excursion) to the appointed place. This is a gathering place--may be promenade lounge, rockin bar D, etc.....they will take attendance, collect tickets, be sure everyone has IDs, and issue a small sticker that you will wear on your clothing. This just identifies you as a part of the group. You may have a blue Ariel or a red Flounder, etc. (not a federal issue if this is lost....)
The CM will then guide you (sometimes with a colored flag--follow the flag) off the ship and to whatever transportation you will use. He/she will again do a head count, and you are off to wherever you have booked.
You will be repeatedly notified of the ending of the excursion and where to meet--back at the vehicle, a certain area of the beach, or whatever. BE there. The CM will again do a head count and you will go back to the ship. They only do attendance by name if the head count isn't accurate.
If for any reason a DCL excursion is running late (traffic, whatever), they will hold the ship. The ship will not leave without you IF you are on a DCL excursion and the group is late. It will leave without you if you have gone off on your own and are not back at the "all aboard" time.
Did I cover all your questions?
