My husband and I had a great time visiting Blancaneaux. Although we went during the rainy season, the weather was warm enough and the rain sporadic enough that it didn't change our vacation. However, the weather was a little cooler than I expected - I wish I had brought more sweatshirts and long pajamas.
The lodge is very beautiful, and we enjoyed the activities, the stable, the wonderful setting, the helpful staff, and the great drinks during happy hour. The concierge had memorized our names and stopped by every evening to help us plan our next day of activities.
Be aware if you go, the lodge is about 2 hours away from the airport in Belize City. 1 hour of this is on a paved highway, the rest is on a very washed out dirt road - even though the distance is about 18 miles, it takes a long time to drive. That didn't really bother us, but it does make it a long trip to head into San Ignacio. Also, while there is nothing wrong with the food at the resort, I wouldn't pay the high prices being charged to eat it back home. And, once at the lodge, you are more or less committed to eating their food.
Other than those logistical details, this was truly a unique and special experience, and we loved the natural setting, the hammock on the balcony, the great service, and the lemongrass mojitos!
