I went last year and loved it! It was a grand day out. There's so much to see. You'll be on your feet a lot, choose shoes carefully. Study the layout of the stalls and work out how best to get round the ones you want to see. It was wonderful to be able to enjoy so many sewing-related displays all in the one location.
All the workshops were booked up early last year, so I booked into a seminar instead. It was interesting, but I probably wouldn't do it again. It was well worth it for a sit down though! I'm hoping to go again this year and will look into the VIP options, just for the seating.
