Flecheiras is 2.5 hours from the city of Fortaleza. We recommend finding a hotel in Flecheiras for the couple of days around the wedding. A couple of hotels are listed on this site. Flecheiras is a fisherman's village, but is quite touristy these days, so you can find many options for accomodations.
We will be arranging shuttles on Friday July 19th and Saturday July 20th to Flecheiras from a couple of pick up spots in Fortaleza and the same to return to Fortaleza.
Uber is widespread in Fortaleza and pretty inexpensive.
