Dumb question about dress being cleaned

Hello ladies,

How long did it take for you ladies to have your bustle done and get the dress pressed/cleaned?

Just curious, because I need to bring mine in. The bustle that I have is very simple, but do they do it right there or do you need to come back?

I'm trying not to keep brigning my dress back and forth to David's Bridal. I'm just wondering if I should bring it in 2 weeks before the wedding instead.

Thanks,
