Woman organizing class reunion TAKING OUR MONEY?

[me]

She's planning everything and taking all the money. I have paid my $35, but I thought a number of people would attend. We graduated with 300+ people and only 20 people have RSVP for Beto's because they don't trust this woman.

We're having it at a Mexican restaurant and the most expensive thing I show on the menu is $11.99.
Our $35 per person is suppose to cover our meal, 2 drinks, and live entertainment. I called the restaurant, they always have FREE live entertainment on the patio and there is no deposit. They will charge your card $50 if no one shows up.

Doesn't that sound expensive to you? I want to question her about it on the Reunion Groups page on facebook but I am unsure how to word it. The event is tomorrow.
More people want to just show up and pay for their own food. What are your thoughts on that? A lot of plates are only $8.
