Save multiple dates

Hi

On a form I have a calendar picker with "MultiSelect" = True.
I wish to be able to select many dates at the same time.
How can I store the selected dates to a database field?
If I save them to a date or text field only the fist data is saved. The other selected dates are lost.
I wish to make an application to book room  reservations.

Any help will be of much help.

Thank you
George
