Does the Weekend Event have to be an over-nighter? How long does a typical night take? How long will it take to receive my order? How many leaders are ideal? How much was changed with the new version? I want to run it alongside a similar 13 week program. What can I do on the 13th week? Is the Weekend Event just a shorter version of the 12 Week Curriculum Kit? What if I want to preview the curriculum prior to ordering? What if PayPal is not working? What payment methods do you take? What shipping method do you primarily use?
