Mileage Advice Man- Mco

Hi Newbie here so be gentle
I plan to visit Orlando next October from Manchester, flights not out yet. I currently have 120k miles and estimate to have around 160k before flights are released. I also have 2 PE upgrades along with a companion flight offer. I will be travelling with wife, 5 year child and infant. Question is i imagine we would get bulk head seats in econ due to infant and sky cot so is the PE worth it?. also unsure of best way to use the offers I have.
any advice welcome
