Just get yourself a wireless license for one AP, they're not badly priced. The longer the duration of the license you purchase the cheaper the per year price. The license part will be LIC-ENT-xYR (where x is the duration in years).
I don't know where you are located, but in AU its about AUD290 for a license, and in the UK about GBP150, both for 3 years - and that's without trying to find a cheaper price or haggle.
That also covers you for support through Meraki if you have any problems and replacement of the AP in line with their standard warranty terms.
