Well, since we obviously can't do this anymore even though it was doing alright and we made some great friends in the process... I've decided just to share our information publicly. Below are some of the custom maps we made for our clients. You may notice the Little Corn map is a bit lacking but that's because we didn't have any clients who went to little corn yet. You may also notice a recommendation to steer clear of a few places. I have nothing against these places, and perhaps you may like them yourself, its just that having been there in person and seeing what they have to offer, and more importantly what their competition has to offer I did not feel their prices were justifiable.
Treehouse - Private cabins on long bay, absolutely amazing. Hot water, kitchen, wifi (thats hard to get on Corn Island by the way) and great service. Around $50 per night
Picnic Center - Best beach on the Island, possibly best beach in Nicaragua. Rooms around $40 per night. AC, hot water, stylish.
Hotel Morgan - prices ranging from $20 to $40. Very nice location, breezy. Good looking rooms with AC. Restaurant has good food for good prices with big portion sizes.
Alal Suite - Upstairs rooms have an amazing view of the ocean and all day breeze. AC not necessary. $25 per night
Some places to avoid:
Arenas beach - Looks pretty fancy. They have gazebos on the beach which are nice. We wanted to go there one day and they wanted to charge us $20 per person (5 of us) to sit in the gazebo. We asked the people next to us what they paid (they were Nicaraguan) and they said $10 for their entire group, which was 5 or 6 people. We asked to speak to someone inside and they simply said "The price changed, sorry". On top of that everything is 2x the price of Picnic center which is literally right next to the place. That being said its really a nice looking place if you're OK with being lied to about the prices and taken advantage of for being a gringo.
Paraiso - Used to be a very nice place, unfortunately it hasn't been maintained and has become quite run down. Some friends stayed there recently and left after the first night because of the poor conditions of the room. A lot of the services they offered online weren't there (like hot water).
Little Corn hotels:
Mostly, just wanted to add one we recently discovered while staying for a wedding on Little Corn. the aptly named "Grace's cool spot" which located right where "elsa's" is on the map above. $10 a night for a simple room, $20 for a private cabin. Probably one of the coolest places I've ever stayed in. All the cabins are actually on the sand, on the breezy side of the island, with the waves splashing just a few steps from your cabin's door. One of not so many hotels on little corn owned and run by local islanders.
As for the ones listed as overpriced, its just that. Too darn expensive. Yemaya for example is supposed to be a "resort" for $300-500 per night. I've been to resorts in Mexico. Yemaya is not a resort. It is a hotel. They also offer a private boat to pick you up from Big Corn, but if I were you I'd stick with the panga. Yemaya's boat is tiny.
Speaking of boats, if you're thinking of going to Corn Island, here is a video tour we made of the largest of the passenger boats that takes you from Bluefields to Big Corn. In this video we are on our way to Rama from Corn Island.
