Top tip Angie,
They drink their own weight in tea! We bought a £5 kettle from Tesco and kept out some odd mugs which we dropped off at the charity shop last night. The kettle is going into the case to keep us going when we first arrive as it is very light. The 2 guys we had worked solidly from 7am until 6pm on day 1 and didn't even stop for lunch. They were gone by 3pm on day 2. It was a very close squeak with the container, we couldn't have got even another small chest of drawers in. They packed it expertly! Good luck!
