Hostel Database Setup

Thanks to all of you for all of your help.

I have a small backpackers hostel and I am currently working on a database
to help me keep track of all of my guests.

These are the two basic design issues that I am running into.

Issue 1. Sometimes, there are 2 or 3 guests staying to gether in a private
room (as opposed to individuals staying in dorm beds which are always
registered separately). Since we rent the private rooms by the room, groups
are considered to be one booking and one stay in one room, even though there
are three individuals. I want to keep track not only of the guest that is
the official guest in my register (the one who pays for the room), but the 2
people who are accompanying him. Why? Because I a) want to know how many
different individuals have walked through my doors b) I want to know the
nationalities of every individual and c) Many times one of the people who
have stayed as a friend of a guest in a private room, will come back on their
own a few days later, and then they might become the paying guest or an
individual in a dorm. Therefore, I want a way that every single person has a
client ID number.

I have managed to do this rather haphazardly...by having a table with the
following fields,

MAIN GUEST 1(TITLE)
clientid1
lastname1
firstname1
nationality1
etc1
FRIEND2 (TITLE)
clientid2
lastname2
firstname2
nationality2
etc2
FRIEND 3 (TITLE)
clientid3
lastname3
firstname3
nationality3
etc3

And I just go in and manually assign a number to each person. Tried using
subforms, could't get them to work. Didn't use autonumbers because I wasn't
sure how to deal with the following Issue 2 below.....

Issue 2. Repeat Bookings. I currently have a booking table which allows
each guest to have a booking with dates, prices, room choice, etc. How do I
deal with repeat bookings of the same person? How do I structure tables and
forms to deal with the infinite amount of booking data that might apply to
one guest since I have no idea if a person will come back 0 times, or 3 times
or 65 times, or if they will be in the same room the next night, etc. How do
I limit my table and form size? How can I pull up a client number say 55,
and then enter new booking records? Should I do this with individual booking
tables? And once again, are my problems solve with autonumbers?


Finally, let me explain why I want this data...

To present real and true financial and marketing data to perspective buyers
of my business.
To answer my guests questions, eg, "How many guests have you had?" "What
country are the majority of your guests from?" "How many Swiss visitors have
you had?" "Are most of your guests under 30?" etc.


I would really appreciate someone's opinions.
