We are doing a soft play party for my 4 year olds birthday. The minimum number of guests is 11 and the maximum is 20. I’m willing to pay for up to 20 but prefer around the lower limit. It’s in July so some people may be away and we don’t know many of the nursery parents socially. We are inviting 4 from NCT and the rest from nursery. The nursery class is around 36 so won’t be able to invite everyone. How many would you recommend inviting to get a decent number?
