a trip around 1-5 of September, in Zion park area

hi!
me and my sister are arriving to Las-Vegas after the burning man festival, and are looking for nice people who would like to join us for hiking in Zion park or other nearby places. something like full day or two days hike trip.
the dates can be around 1-5 of September.

anyone wants to join us? we are also open for interesting suggestions :)
what would you recommend us as a 'must to see' trip over that area?

(but we do not have any knowledge in ropes or canyoneering)

thanks!
