The business opportunities for an indoor playground is vast as you can consider multiple options like Kids crèche, kids play areas in shopping centres, business space and educational sectors.
Be warned on the outside soft play centres look like a fabulous business.
During school hols and wet weekends they look packed and everybody thinks the owners must be rolling in it!
However the business is totally weather sensitive and when the sunshines nobody comes in, but the bills still have to be paid.
During the week when the kids are in school, customers can be very limited and with social pressures many little ones are in day nurseries (have a look in yellow pages at how many day nurseries there are).
