Confusion Before The Wedding

On July 11^th, 2012, Tiffany sent an email saying that I was more than welcome to come between 3:00-6:00pm to drop off any items and/or decorate on the day of the wedding. I responded that we'd be there at 3:00pm. We later received a reminder from Tiff on August 14^th about decorating a day prior to the wedding between 3:00-6:00pm. However, this turned out to be a disaster, as we were not even allowed to go in and decorate the ballroom on the day of the wedding. My fiancée, now husband, and some family members and bridesmaids showed up to decorate the hall at 3:00pm. They were told by Tiffany that no one was allowed in. I then showed up at 3:30pm to talk to Tiffany and am told that she said that we could drop off decorations and see what her staff has done as far as set up but that we couldn’t decorate until 4:30pm. She also said that we couldn’t bring in that many people to help, even though we only had an hour and a half to decorate a whole ballroom. (It had been previously stated twice in 2 separate emails that we could decorate from 3-6pm.)
