Our visit to Coalville was in early March 2013 and unfortunately the lake next to the house was dry due to construction on a nearby dam. Despite the dry lake, the house was incredible.
We had an absolute blast at the house. The house itself is massive and you can tell the owners spent a ton of time and attention to every detail in the house. In fact, if you wanted some quiet time it was very easy for you to "go missing" for a whole day in the house. There's no real reason to ever leave the house when you get there besides to get food. There's tons of entertainment. An awesome movie room, pool table, darts, ping pong table, poker table, 2 xbox 360's, dry sauana, massage chair, hot tub, and outdoor fire place. The only thing they're missing is a foosball table.
The house was extremely comfortable for 7 people. Everyone had their own room and bathroom. The owner was gracious enough to include shampoo, body soap, and towels (something that we all forgot to bring).
The kitchen is stocked with everything you needed to cook plus they had a commercial dishwasher that washed dishes in 90 seconds!
Jack, the owner, was a pleasure to coordinate our trip with. We didn't have any issues with the boring stuff and everything went along smoothly.
Overall it was a very fun and relaxing trip. We will definitely be coming back.
