I saw a tour company offering a tour of Poás, Doka Coffee and La Paz waterfalls for $100. This seems pretty steep, and I was wondering (1) if it would be cheaper to book something like this when we get there or (2) if it would be possible to do something like this solo for less. I know there's a bus that goes to Poás every day; is there a way to get from Poás to Doka or La Paz, other than hiring a taxi? How much would a taxi be, give or take?
Also, a general question -- is it cheaper to book tours when we get there, in general, or is it better in advance? I speak Spanish so I'd have no trouble working things out on the fly, and every other trip I've taken I've booked things as I wanted to do them, not in advance, but there's so much to do in Costa Rica that I feel a little overwhelmed. I wonder if it's worth it to wait until we arrive.
We'll be starting our trip in Alajuela and this type of day is why we're planning on staying for an extra day, so I'd love to be able to work it out.
