We stayed at Las Hades in Manzanillo Mexico a few times. They have an iguana sanctuary or something there. You can be sitting on a chair by the pool and one or a couple of those huge suckers will come lay under your chair for the shade. They’re all over the pool area. Hubby always laughed but they unnerved me. I couldn’t really fall asleep or relax because when I did I’d wake up and those suckers would be under my chair. Lol
My wife has an inclination to stand up on the table when they come past and she’s the one who should be used to then. They are pretty harmless unless you are a cat or small dog. The main prey is supposedly the rats that swarm restaurants.
