I think it will bring some in. Not in any huge numbers, though. The major uplift will be in ordinary supporters spending money on booze and food in a bigger, modern stadium with great facilities.Anyone who thinks this stadium is going to suddenly bring in foreign tourists are deluding themselves.
No one is going to buy a tourist package to see a club fighting relegation and getting beat at home to Luton ect.
The club needs to build a successful reputation on the pitch first.
