Could you ask if there is a possibility to go to the Monday? Stupid hospital policy not to induce over weekends, I was exactly the same and asked what would happen if we left it to the Monday to be induced and the answer was that they would monitor me on Thursday/Friday and potentially over the weekend too and then I would 'check in' on Sunday night and be induced on Monday morning. I sooooo wish I had done this, we went with the Thrursday night/Friday scenario and I simply wasnt ready and ended up in c/s I know that the same thing may have happened but that extra 4 days may have made a big difference.

I know at that point that I had other issues that made me not want to sit around on the weekend being monitored (being a bridesmaid in a wedding ) sounds like a lame reason to induce now but by then my BP was starting to go up because I was stressing out. If I was you I would tell them you will not turn up (what can they do?) and what you can put into place for a 14 days over induction if needed.
Sorry for the ramble but you sound really determined and I hope you get the labour you want hun. Good luck!
