Table plan sign board - help

Hi, so I'm getting married in 16 days and really need to order my table plan sign. However I have 2 issues. I'm not sure if an A1 or A2 board would be better (I have 8 tables and 69 people total). Also, vistaprint seemed to have drastically raised their prices so would anyone recommend another site that I can get a good quality, cheaper foamex board with reasonably quick delivery?
