I would take my more expensive machine . Once set up will stay for length of quilt weekend. From personel accident make sure the machine can't fall over and well protected the sewing machine trolley still needs this protection. Recently I had my expensive machine in one of these trolleys and had to do an emergency stop .. The handle of machine went under the top of machine. Luckily a lawn mower repair place opposite where I was looked and repaired it for me.
Most of all enjoy. The weekend and have a go.
