There are a few things to like about your seats and a few things to dislike. Section 121 is on the lower level just beyond the infield - providing a good landscape of the field without feeling too far away. Your seats are also on the aisle and close to the section tunnel, which makes for quick escapes to the concourse and its amenities.
Unfortunately, row XX is the last row in section 121. The last two rows (including WW) are underneath the 200 level overhang. At an outdoor park, these seats would be popular for their shade. But at the Trop, it simply means that the view of the field is somewhat obstructed and you may feel rather confined. In particular, tracking fly balls and pop ups will be difficult - as will seeing the entertainment and score boards around the park. You won't have any trouble seeing the pitcher/batter exchange, but the overhang will be an annoyance to fans who keep a close eye on all facets of the game.
