From the airport you can take a taxi for around $30 to the hotel. If you take a bus from Quito buy a ticket to Atacames, not Esmeraldas. As Atacames is 15 mins away and Esmeraldas about 50 mins. You can take another bus from '5 esquinas' any bus heading south that say (Muisne or Chamanga), just tell the bus driver you want to get off at the end of Playa de Same at Cabañas Isla del Sol 'con el rótulo celeste grande'. Or a taxi for about $8.
