Ask to speak to the head of the parent committee and explain that it's too much. The PC should be prepared to help with the costs for those parents who cannot meet this, and there will be a reasonable number who will struggle with that amount. DO NOT under any circumstances allow yourself to feel shame that this is hard to meet. This is an unreasonable expense in the current climate.It may be too late to change the plans, but I would imagine that a party held in the school grounds would be far more cost effective and just as, if not more, pleasant than a trip.
