Parasailing/ Snorkeling on 7-mile beach

[luvstocruise711]

Just read about parasailing being available at 7-mile beach. My daughter and nieces would like to try this. Does anyone know if any of the vendors are better/ worse than others. Also, they would like to try snorkeling. Is there any particular section of 7-mile that we can do both parasailing & snorkeling? Snorkeling doesn't have to be spectacular-- they just want to give it a try. I've been reading this board for most of the day trying to finalize our plans and now I feel more confused than when I started! Way too many options!! Sea Grapes beach sounds nice, but does it offer both of what we want to do? Any help will be appreciated! Thanks!!
