Well, they weren't quite all consecutive, but the most park-intensive stretch I've had was a bit on my drive from CT to CA last spring where I hit 19 parks in 22 days. However, within that stretch, I didn't run more than 5 days in a row at parks without taking a day off.
Just for the record, the itinerary for that one was CP, Day Off, SFNE, Whalom/Canobie/Funtown, LC, Day Off, SFA, Dollywood, Lake Winnie, SFOG, Visionland, Day Off, Jazzland, Day Off, Magic Springs, Frontier City, Joyland (KS), Day Off, Day Off, SFOT, SFAW, SFFT/SWT.
Outside of that trip, I've had a couple stretches of 6 days of consecutive park visits (and have one more planned around SRM this year), but they weren't quite as bad that. One of the few things about college life I'll miss is the ability to plan trips like these.
