I think the problem is that the rooms are two small to add two beds. Just got back a week ago, and we had two couples and two kids, the best we were able to do was one extra bed per room. In Sevilla we stayed at the Hesperia and they couldn't do even that. They did make an effort to provide adjacent rooms (not connecting, those are apparently also rare). We enjoyed the Hesperia, it was close enough to the Cathedral/Old town area to walk (about a mile I would guess). The Hesperia in Toledo was much nicer.
