4 weeks for me too, we're getting married on the 23rd as well!
As you say, its just paying people and making lists. I have 2 major worries, one being that my dress hasnt arrived yet but Ive been assured it will be here in time. The other one is our Best Man who has become very reclusive as his girlfriend has depression and he doesnt like to leave her much. I could turn this into a woeful whinge but its not my thread.
Seating plan to sort out and table plan to make, favours to make up, hair and makeup tryouts and I guess thats it!
