Children Sharing Bedrooms - help??!

[zazas]

Just need opinions here..... we are going to buy a new house as we have outgrown our existing one. It is to house me, DP and my DD and DS full time and DP's DS and DD on a one night a week / every second weekend basis. We are looking at 4 bedrooms and I feel that my two will have own rooms and step kids share when they stay.... DP not so sure as his DS wants his own room like he does at BM's but so do my kids want their own rooms! I get emotional about this (shouldn't but do!) but believe that since my DD and DS live here all the time they should get first choice of rooms in my opinion. Probably not really relevant but it is my house that we are selling to finance this move.

I have a feeling that we might go down the girls in one room / boys in other route at least until they are older. Stops any arguements or hurt feelings about who has what. Now is it best bunk beds or two single beds in order to feel like it is your space?? Thanks by the way for the support, it isn't easy juggling so many people's feelings and needs in a step family.
