Throughout the DVD, each of the members were asked what they'd like to do in the summer. Also linked are their answers to the same question for the PokeMo questionnaires, translations courtesy of Rokun. This'll also allow you to make a consistency check, whether or not it actually their answers are actually what they want, or are they just coming up with an answer on the spot, as it were.
What they'd like to do in summer
PokeMo answers
Maimi: Marine sports - banana boats, wakeboarding
Nacky: Camping - she's never gone camping before
Airi: Every year she says that she'd like to go to a summer festival, or play with fireworks, so this year she'd like to add BBQ-ing to that
Chisato: Take pictures of sea fish - she goes to the sea every year with her family, and since she sees lots of fish while swimming, she'd like to take pictures of them
Mai: Go to the sea and watch fireworks - she hasn't gone anywhere this year, so she'd like to go and watch fireworks in her private time
