dd announced a while back she wanted a swimming party. Had hoped to join up with another girl who shares same bd'ay(and split cost 1) but they each have different ideas !
Swimming party would cost £100 minimum plus food but it would mean no tidying up and minimal hassle with 2 hours entertainemnt laid on (can choose games, bouncy castle etc for after tea).
Alternative is a bouncy castle in our garden plus games /activities. How much is a bouncy csatle to hire roughly? This would be weather dependent and space for a contingency indoors is fairly limited. Still would have to do food plus provide entertainment ourselves.
