Just wanted to let you know that his 'best days' charts alone are worth the subscription and the forum for your specific month of travel gives great information. I have used him 3 times now and wouldn't hesitate to recommend the site. We never encountered busy parks or huge lines except for one day when we went to Magic Kingdom on a 'red day', because it was the only CRT ADR I could get. The park was packed and we stayed for just 1 hour after the meal before going to a different park to escape the crowds. The difference that day was amazing.
