The party room is very large and includes two bathrooms (which are also open to the public using the park). Montgomery Parks says that the room accommodates 60 people, so it may be a little tough if you have 50 children + 50 parents, but there's a good possibility a lot of parents will just drop their children off at that age and take siblings to the neighboring playground or carousel. The party gets its own private train ride, and I have never seen my friends pay for tickets above the 20 maximum, but they could always change their policy and charge $18 per set of 10 extra tickets. If it's raining, there's no train ride, so you have to be prepared for that possibility.
You have to provide the food, paper products, special decorations, etc., but it's one of the least expensive party ideas in the region for large groups of kids, if it's not too far for you.
