No, unfortunately, the new one on the 27 isnt as big as the one near Medieval Times. They still have a good range of stuff though, and it isnt small by any means!
Another option is the one just off of Sandlake Rd. This is massive and handy if you have been visiting the I-Drive area. Its about 2 miles down Sandlake Rd.
I would avoid the Medieval times one this year as the roadworks down there are awful.
