We have done it before and had a table right on the glass to the point the orca swam by and soaked our food. I booked pretty early but then there was a Black Friday sale and rebooked hope that doesn’t mess up tables to much.Our experience in the three times we've done this is similar to what CAPSLOCK is saying. Twice we booked really early and had great seats. Once we booked day of (last minute decision to go) and had one of the poorer table locations (We still enjoyed going though).
