Changes after Contract signed

I signed my contract already and there are a few things that I wanted to work out with the hall when I sit down with them again.

Anyone have gone trough this and do they usually work with you?

i don't know about your Reception Hall, but mine has worked on a few things with me already. THey are usually good about it. You can pretty much add/delete/edit anything you want until you make your final payment.

The only thing i would be weary of: If you tell them you are going to guarantee for example 175 and then you want to change it to 150, they might want to raise your price per head..

Thanks :)
I am just getting ideas from other people of what other halls have included and not included and figure it is worth a shot
