We spent three beautiful nights at Iguana Roost. Peter and his family are amazingly gracious hosts. The property is beautiful. Keep your eyes peeled for all of the beauty around you. Iguanas and hummingbirds and butterflies, Oh My! The dogs are wonderful. You'll rest easy knowing they're watching the front gate.
Don't pass up a meal at Ko-Ox Han-nah. In fact, consider going there twice as the menu is amazing. Pass on the cheeseburger, really, there is delicious curry and an amazing lamb stew on the menu...do us both a favor and don't. get. a. cheeseburger.
Do make the trip to Cahal Pech (take a cab there, the trip is all up STEEP hills). Take water with you. Lots of water. You'll need it. Climb, explore, look out into the fierce jungle around the site. Take it in. And, if they are still doing excavations, talk to the people working them. SO much cool stuff to learn about that site.
Don't fear the lack of AC. Do make sure you bring clothes that are not prone to causing chafing. There is no real respite from the heat and very little option to not walk. Be comfortable doing so. Trust me on this one.
Welcome the rain if you travel in rainy season. It will help with the heat and it won't last long enough to cramp your plans. It will wash everything around you in sparkling glory and leave behind the most beautifully fresh smell.
Don't open wine by pushing the cork into the bottle...it makes an enormous mess and will nearly blind you. The process of cleaning up the mess you made will have you drinking and you'll learn later that you are a sloppy drunk. Also, wine doesn't wipe off of flat finish paint, which will force you to have to inform your host you're a putz and leave you looking like a complete cad. The best bet is to stick to those tiny Belikins or a screw top bottle of wine.
Go to the market. Go on a day the Mennonites come in. Get fresh sliced fruits from the vendors. Get a bag of fresh coconut water (skip the canned stuff at the stores).
Take Peter up on his offer to assist with travel and outing arrangements...he'll refer you to top notch outfits. No one can possibly explain how amazing the ATM tour is. Just do it.
Your stay WILL be amazing. Peter has a perfect set up for your home base in San Ignacio. There is SO much to take in. I promise you won't be staying long enough to enjoy it all, but definitely try anyway!
