Should we invite the whole class to a five year old bday party?

Should we invite the whole class to a five year old bday party? It's going to be a lot of kids, as there are nearly thirty children in my son's kindergarten class. Should we invite them all to his birthday party?

I would think ,yes,if the answers below are 'yes':
1) is there enough supervision to maintain control ?
2) will the budget allow ?
3) is there adquate space ?
4) need clean-up crew ?
5) will this end in a nervous breakdown ? (just kidding LOL)

Good Luck and God Bless !!

Also it's a very slim chance everyone will attend. It's my understanding that these days you can't send invitations to the class unless you invite the whole class however that's not saying you couldn't JUST invite boys or invite everyone AND their parents.

maybe just invite the boys and if your son has close friends that are girls invite them too.
