Is it possible to buy meals on-site

[Sam Hartman]

This tends to change venu-to-venue based on how catering is handled.  If
we discover that schedules have changed and we need to take a meal in
the venue that we did not plan to take there, is it possible to buy that
on site, or is it important that we make sure to pay for any meal we
might possibly take at the venue up front as part of our registration?
