largeglassofred, some mums have had home births with dts. I found some lovely, and inspirational stories about it online, though it wasn't for me. I did want a home birth but not once I foudn out there was two.
I was barely mobile at all by the end of mine, so being tied to a bed wouldn't have been an issue!
I'd do as must research as you can, then form an idea of what you would like, and be prepared to fight for it within reason and while stil being open to changes which are necessary because of complications with twin births.
