I was going to suggest exactly what @Blossom74 and you had in mind
Will 1 cot fit in your bedroom that you can put them both into?? It's not going to be an issue to sleep them side by side on their backs until they start to roll so you'll have a good 3 months or so up your sleeve there before they do.
Trust me when I say that you won't want to be getting in and out of bed every 2-3 hrs to then have to walk into another room to feed them when they're newborns and change their nappies/resettle them etc afterwards. It's exhausting as it is to do that when they're in the same room as you in the beginning!!!
Plus it'll be winter too Luv so my advice is if there's anyway you can have them in your room at least for the first few months then make it happen however you can even if that means buying a portacot with a bassinet attachment for eg as they're smaller than a normal cot so might be easier to get that in your bedroom instead??
P.S...There's things I've done and do that are "frowned upon" Luv but at the end of the day, as long as it's not anything unsafe/dangerous, then I do what works for DD and for us!!!
