Edit...
Could not delete this message/topic, maybe a mod could do it for me.

I uploaded the largest blank map into the download area so I no longer need one from somebody else.

The largest possible is the sandbox park.

Well actually, the largest possible can be set up using the custom scenario tool. You can set up a park a lot bigger than regular sandbox parks. After you have created the custom scenario you can copy and paste the file under the "Parks" folder to play it as Sandbox

Nope it's the same size.

When you open a new file it is the same size but you can make it larger... that's what I used to build my park "Worlds of Adventure" IT IS HUGE!

The largest size as far as I know is 254x254 which is what I finally just made one and saved it so that I can always start from that size if I want the largest park. I think the default sandbox size map is 128x128

Sandbox is 128x128. Using custom scenario editor, you can change the map to be much larger than that.

Thanks for the information!.
