I went for my 8th and likely final time yesterday. It's disappearing all over in my neck of the woods. Would love to go the July 4th weekend, but who knows if it'll still be around.
I've been 12 times but didn't go this weekend. Probably won't make to the holiday weekend (too many ballgames) but will wait until it hits the dollar theaters to see it some more times (much easier on the budget: $7.50-matinee vs $3 anytime/1.50 Tuesdays).
Unfortunately, I've only been to see STiD once...
Circumstances have been such that going to the movies, is a rare treat now-a-days.
As for multiple times of seeing a movie...
I do remember an occasion back in December of 1974 when I was stuck in Washington DC for a four day weekend of sight-seeing...
I arrived Friday morning just before one of the biggest snowfalls in DCs' history socked in the entire North East.
Stuck in a mid-range motel (two stars) in Alexandria for four days, the only saving grace was that right next door, was a two screen theater which happen to be showing "The Towering Inferno" on both.
(back then one didn't wander around Alexandria alone day or night, unless one had no choice. Especially if one was a
lilly-white honky-boy 
)
If I remember correctly, it cost between $1.50 to $2.00 to see a movie.
I saw
"The Towering Inferno" 14 times that weekend.
I remember actually only paying about $8.00 total for the whole weekend to see the movie, as for most of the shows, I was pretty much the only viewer and the theater owner was kind enough to
not kick me out, between viewings.
After I explained my circumstances, he was quite friendly and we ended up enjoying each others company for several of the shows.
(as well as some "
after hours" fun in my motel room starting Saturday night. I was quite the
adventurer in my younger days 
)
I don't remember how much I paid for the boxes of popcorn and soda. (though much of it was on-the-house, after we became "friendlier")
There is much more to this story, as I returned to that particular motel on many more occasions for weekends of fun and actually spent at lot of time wandering around Alexandria.
But that's a tale for another time...
