i don't know if this will work:
have a column that starts off as todays date,
if when they go to this page, it adds one day to the date in the database,
on the page it checks if the user's value is equal to the todays date,
if the date is correct they can see the page,
if the date is for tomorrow they can't.
then the next day comes and it will be the right date and they can see it.
make sense?
