Oh, 5 days is a lot there. But... go golfing! How many people have golfed in the Amazon jungle, but careful putting you hands in a water hazard.
1/2 day to the zoo. 1/2 day boat to Belen.... not much more. Watch sports in English upstairs at the Yellow Rose of Texas? Chat with the chicas on the malecon? Do not know the multi-day tours, but for sure somehow get immersed in the deep jungle to appreciate that aspect. And yeah, the whole ayahuasca things is a bit weird, una estafa.
