My reception is going to be at a hotel, and they offer something called the Fairytale Package. They will drape the entire ballroom with a sheer white fabric that runs floor to ceiling and then place LED lights in the color(s) of our choice every 10 feet. This helps cover up extra exits (it is a ballroom with 3 sections and we are having them all open so there are a lot of exits) and can have sort of a "wow" factor (I think). We saw the ballroom draped in the sheer fabric but the lights weren't set up yet so we couldn't see that. I loved the way it looked with the draping, but I just worry about the lights. In theory it seems great and looks cool in pictures, but I worry that it will be too dark and harsh on the eyes.
My idea is that we would have purple LED lights and then the centerpieces on the tables would have a lot of candles to brighten it up. Does this sound alright? Or does anyone have any personal experience with LED-lit rooms? I also worry that it'll look more like a club than a nice wedding.

This is kind of what I expect it would look like, just with added draping around the room.
Thanks!
