What seasonal park has the most operating days?

Does anyone know what seasonal park has the most operating days? It looks to me like it might be PKD since they open in mid March, but PKI also looks like they extend their operation the furthest(November 4). Anyone know exactly?

SFMM maintains weekend operation during Dec., Jan., and Feb., but I guess that's not really seasonal.

Great America and Marine world

PGA/SFMW parks, virginia parks, PKI. I think PKI they opended on March 24 along with the others, but have exteneded operation.

Not MLK's words but mine..I have a Dream! I have a DREAM! I HAVE A DREAM!
I have a dream! That SFMM fans will be able to walk hand in hand with CP's!
AND no ONE cares what a coaster is and what a coaster isn't!

PKI opened April 7th this year and I think April 6th next year, so that is quite a few days and PKI will be my first and last trip of each year if they continue to stay open for a November weekend. I am glad that Indiana Beach opens as early as the first weekend of May, but they close on Labor Day. I don't care for that. That means only 4 months of operation for Indiana Beach compared to PKI's over 7 months.

Coasters are like a fine wine, they get better with age.

Six Flags over Texas opened March 3rd and is closing January 6th. I would believe it is the longest, but not 100% sure :)
