The zipline we did (just outside Tikal) also had just two guides. One to send and one to receive. We tipped them both once we got back on the ground.

And yes - total blast! I froze on the first platform and thought I was going to climb (or crawl!) back down. However my husband and another guest we'd met at Crystal Paradise had both already gone - and I decided I wasn't going to be left behind!

My reality check bounced.
