having to re-plan on hen do...

hi guys - my original hen do involved a villa about an hour or so from barcelona, and would have been awesome except that the travel is just b**ggering the logistics up and adding a good £60 minimum onto costs, awhich i just don;t feel i can ask people to pay. also two or my closest uni freinds are refusing to come on cost grounds (fair enough) and an old school friend has dropped out, which raises costs for everyone else.

all the flights are booked into barcelona, so am thinking of asking the villa for our deposit back (it's still a good 4-5 months away) and trying to find us all somewhere to stay in the city. basically this whole things has made me really stressed about asking a group of people, many of whom don;t know each other, to shell out loads of money to come somewhere a little way OUT of the city (even though the villa was cool) and then have to trek about, and some might want to do their own thing in the day, so think staying IN barca instead will work a lot better, and more importantly be cheaper for people....

so........... does ANYONE know somewhere cheap but nice in barcelona where we can stay for less than £100 for 3 nights?

any help appreciated as i've had to plan this more or less without my bridesmaids (not having a go at them, that;s just how it;'s ended up) and really sick of the stress and planning!
