Simply the best hotel I have stayed at for Gencon. I have been to 15+ Gencons and have always wanted to stay at the JW Marriot. It did not disappoint. Rooms were extremely clean, roomy and comfortable. Open gaming was downstairs and convention 5 minute walk. If the JW Marriott had a pool, it would be the best hotel I have ever stayed in period. It still ranks top three. I would definitely stay here again.
