Upon first glance, this seems like an ambitious itinerary for 3 weeks given how long it will take to get between some of the destinations. We can’t really say more than that though without knowing more about what you’re looking to get out of your honeymoon/the things you’d like to do/how busy you want to be, etc. Because this type of review is very time consuming, we offer it as a service. In an itinerary review (more information here: https://www.twoweeksincostarica.com/itinerary-help/), we help people figure out the best order for their travels, amount of time to spend in each destination, and the best way to get around.
