It really was such an amazing time. You certainly picked the most extreme ziplining I've ever seen. Compared to the one at Los Lagos (lame), I couldn't have been more thrilled and terrified at the same time. I tell friends we were 1/3 the height of the CN tower off the jungle floor (which is true) and they are shocked. I can't believe I was risking life and limb, but we survived. The horseback riding was also a highlight. The guide was awesome and we had a fun experienced group so he let us run a bit. The hike down was easy and the waterfall impressive - Jason made it close to the centre as he's a strong swimmer, but I was amazed how strong the current was (and how flimsy my bikini was). Thank goodness I'm fit as the 375+ steps back up are challenging.
I can't say enough about the hotels. Certainly lots of hiking back up to our room at Los Lagos (again I'm fit), and being in the B-building at Costa Verde meant much less hiking. Not sure if you mentioned the local bus, but that should be a key selling point - 425 Colones is so cheap and the bus comes every 20 minutes. We only hiked up from the beach a few times and mistakenly took a taxi once.
We saw more wildlife at our hotel than we did at Manuel Antonio. We ended up taking the city bus there and not doing a tour because they are jam packed with people using telescopes to try and see a tiny spot of grey that's a sloth. Meanwhile the gardener showed us a sloth just next to the pool, the howlers howled every morning, a white-faced monkey walked by the pool one day, and a group of squirrel monkeys lived in a tree behind building B (we were lucky to see them swarm in one day, leaping and bounding). My friend jokes that the Slow sign is "Evolution in Reverse".
Truly an awesome vacation, so I've got to work a lot more to make some money to come back!
