What do you think of an indoor play ground for Toddlers, where parents can enjoy a good cup of coffee.?

The little ones could play while parents could enjoy a good cup of coffee and chat with other parents. Any suggestions? I don’t have much business experience, but I’d love to take a plunge…I’m looking for encouragement as well as some constructive criticism.
Thanks
