....where her sibling broke her arm at a birthday party?

Details: DDs 1 & 2 were supposed to be doing one day of "camp" per week at a kiddie gym/gymnastics venue this summer. After doing one day of camp, DD2 broke her arm at DD1's birthday party, at this same venue.

The venue, to their credit, is being great, and has agreed to do whatever I want about the camp in terms of a full refund/partial refund/forward credit for classes.

While I don't REALLY hold the place responsible (accidents happen!), I have not yet sent DD1 back for camp (this week will be the second session that the girls miss). DD2 really can't go; there isn't much for her to do that isn't a "fall risk", which she is meant to avoid while her arm is casted and immediately after. It's partially to avoid jealousy, and partially because...well...I don't know. I'm just slightly reluctant now. But....this is really my only way to get out and about during the week without the kids, unless I book a sitter, for the remainder of the summer.

In my case, what would you do? (Poll below, but I'd love to hear explanations).
