I have worked as a tour director (tour guide) and have checked in groups more times than I can remember.
It is different than checking in a person or a family.
A few questions:
When is this trip?
What country?
How large is the group? How many rooms?
How many hotels?
Are you working with the sales department or group department of the hotels? If not, you need to be. If not, you could run into big problems.
All the hotel reservations are in my name. Do I take everyone's passports from them at hotel check-ins and hand them back to them with the room key?<
How are going to do this if they are all arriving separately?
What you do is request their information prior to departing on the trip...Name, address, passport information (name, birthdate, passport number, expiration date, place of issue). You then compile it as a list along with room type information--single, double, twin-- for each person or couple. This information is then sent to the hotel a week or two prior to arrival. (Or the hotel will tell you when they need it.) They need this information prior otherwise check in will take forever. They also need to register the people into the rooms. You can't keep them just under your name.
When you work with the sales/group department, they will know you are coming and have your keys ready when you arrive.
But each hotel is different so you have to know their procedure.
The other thing is this. Hotels don't really look at regular reservations until a day or two ahead of time. If they see a number of rooms in your name, and don't know it's actually a group, they may think this is a mistake and cancel some of them. That's why you need to let them know in advance what is going on.
Do hotels allow you to give a printed passport copy so I dont have to keep taking they're passport from them?
Most do but you need to check with the hotel. I never had to collect passports at each hotel. The hotel already had that information.
Who is paying for the rooms? If each person is paying their own, then the hotel has to know that otherwise you will get the bill.
IDid you book each room individually? If so, you probably could have gotten a cheaper "group" rate by working with the hotel.
