Hello ! In reading through the forums I'm still not understanding if it is possible to go from Cartagena to Tayrona in the same day ? We are planning to stay over night in Tayrona in Hammocks. Can we get there in a day, and in time to get a Hammock? Do the hammocks sell out ? We plan to hike in, instead of taking the boat ....reading the boat ride is very rough. Is it better to stay in Santa Marta for a night and then go in to the park in the morning? Really appreciate any suggestions ! Thanks !
