Making an Exit: Bubbles or Sparklers?

I'm waiting to hear back from the Social Director at Prestonwood as to what rules they have regarding the sendoff at the end of the reception, but in the meantime I'm contemplating whether we want to exit to bubbles or sparklers. I'm not afraid of sparklers at all so that won't be an issue for me, but I think that since our sendoff will be around 11pm that the sparklers would look better than the bubbles at night. I've found some pictures of both at Prestonwood to give you an idea of what it would look like.
