I've been doing training for about 30 years and have experienced the good, the bad and the ugly. Definitive is definitely one of the VERY BEST! Spacious rooms, tasteful decor, good food, safe parking, good location (near the airport and right next to a hotel) and 5-star service! They also pay attention to the small things such as the lights near the screen are disabled so that they don't shine onto the screen, they provide lemon water, there's a fridge with filtered water so if you run dry you don't need to wait for your bottle to be replenished and the owner is hands-on, which makes a big difference. As Arnie says, "I will be back"!
