Decorating the venue yourself?

More questions .. from me! My potential venue is a do it yourself kind of deal. The chairs and main tables will be set up how we want it, but everything else (linens, lighting, drapery, centerpieces (obviously) and so on) is going to be on us. The maximum time we can rent the venue is for ten hours, which is plenty of time .. as our venue books up quickly, we are trying to establish how much time it might take us to set up ourselves. I'm not interested (at this moment) in getting a DOC. I'm likely going to rent the bridal suite in the venue so that I can set everything up and get ready in the same place (and my bridesmaids are eager to help), so I'm curious: To those of you who are setting up yourselves, how much time are you giving yourselves? To brides who have already married, how long did it take you? I'm sure our venue will be able to guide us as well but we are hoping to book and sign a contract the same day we view the venue, so we're planning ahead.
