Netty,
We flew out on a Thomson 767 last March to Barbados and everything went perfect. Worth the upgrade to Premium seating, more leg room, comfy seats. If interested seats 7a/b are excellent, 2 windows and being on the port side good views of your ship when coming into land.
Also, if travelling down by car and looking for somewhere to park, I can recommend - Meet & Greet at T2, in March it was £49.99 for 14 days, same price as Airparks but right opposite T2, so no buses, no waiting. At Manchester we had priority check in, fast track lane through security and into the concourse, took 15mins.
