Could I have some help please over my worrying!

On 2nd July 2013 I'm going to florida, with thomson.
1) Will thomson have the dreamliner by 2nd july?
2) If not, will I be going on a plane to florida or will thomson have no replacement planes? (urgent this point is)
3) Will I be payed back if they cancel the holiday due to no planes being able to fly me there?
Thanks I really really need to know!
