Her pocket money is not enough to cover such outings and taking her on these day "trips" is part of welcoming her to your family and giving her a full experience.
Obviously if it is financially impossible you do not have to invite her along for everything, but you should pay for her basics (admission, meals, drinks, locker for her purse, whatever) when she does come with you. If she wants something from the gift shop that's when she breaks out her own money.
If Aupair goes to a waterpark with her purse then that's her responsibility and she should buy a locker herself.
