Little advice needed. I'm visiting LV next week and am looking to set 2 or 3 appointments (got just one set so far).  Since I have no references, I'm finding I may need to sign up for Date Check, Preferred411 or Roomservice-2000.

Anyone tell me which is the best value and most versatile?  Thanks.

I'm not sure which one is the best but the one I happen to be a member of is Preferred411.com and that seems to work out well for me.  While all are effectively national sites since we are in the internet age I think RM2000 tends to be more popular in the Midwest.  I have heard of Date Check but have not used it nor have I heard from anyone who used it before so I can't speak to that.
