I did RioShuttle on my last visit. For whatever reason the driver felt the need to ride all through the crowded streets of Leblon before he backtracked to Ipanema. Also on the return it was raining that day so we decided to head to the airport early and hang in the lounge. We emailed RioShuttle and had to wait for a reply as far as changing our time of pickup, which we could not. However, since it was not a prepay it was not a big deal and we just cabbed it to GIG.

So like SuperShuttle here in the US you trade time for money.
