Thanks for that lap-lap.
Hopefully - and I think this is good news - the pictures you posted are for a B767 aircraft, and the flight to Florida for the OP in an Airbus 330. In the case of the airbus the 2+3+2 does indeed give extra width (economy is very cramped at 3+3+3).
The picture you posted is noteworthy in the sense that the 'premium' cabin as shown is the same as any normal economy in a first tier airline.
