My husband and I (both seniors) will be arriving at LIR going to the JW Marriott. I do have a quote from Liberia Shuttle(private shuttle) but we are wondering how difficult it is to take a shuttle to Tamarindo and then a cab from town to the JW. Trying to save a little $$$ but am not sure if it is worth all the extra effort. Has anyone ever used Liberia Shuttle? Any suggestions would be appreciated.
