These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: "Linger" by The Cranberries and "The Creator Has a Master Plan" by the Brooklyn Funk Essentials really stand out as gems in a movie that's filled with otherwise forgettable pop/rock.
Hollywood Pudgy: Gaby's mom wants to send her to a weight loss camp called Camp Slenderella, and later remarks during Parents' Day that the camp thinned her out. Actress Melody Kay was quite visibly NOT overweight at any point during the movie.
Trish is played by Marnette Patterson, who would later play Christy Jenkins.
Hillary Tuck, who you might recognize as Amy Szalinski, plays Betty Stoller.
A non-child example: Kate Mulgrew plays Trish's mom five months before Star Trek: Voyager's TV premiere.
Values Dissonance: Audiences here in the 21st century would be incredulous that any parents would blindly send their children away to random summer camps without doing a little more research into said camps or the camp representatives that Van Welker claimed to be.
That and letting their kids go off with a complete stranger, with a criminal history, with no experience as a camp counselor.
What an Idiot: Had the kids followed The Con through to the very end and not started celebrating an early victory, they could have intercepted and sidetracked Polk at the front gate, and made sure that all the parents had gone, thus ensuring the success of the phony camp.
