Well I had a great weekend - all by myself!!!! Once I had decided (thanks to you all) that it was OK to make her go with her Dad, my daughter still complained but much less. Then when she went she mostly had a great time I think - just a couple of 'moments'.
So thanks for all the help and hang in there brave1225 - as always with kids, the clearer you are about your decision the quicker they 'get it' and the easier it is for EVERYONE - including them.
