Hi Doug,
This might not be the best forum to look for traveling companions, as the audience is members-only. If you are looking for expats already in Ecuador to explore with, you could try Facebook groups. Just search for groups with “expat”, “Ecuador”, or the name of the cities you want to visit.
To find travel companions, you might also want to look into forums like craigslist. In fact, if you Google “travel companions”, you will find several websites that help match up people with similar travel goals.
Good luck, and I’m sure however you choose to travel, you will enjoy your visit to Ecuador.
