To 'hold on' or 'hold on to' means:
With these meanings in our mind, now compare the sentences in the question. i.e.
(1) "... hope. It's the only thing they have to hold on to."
This means they have nothing to help them except for their hope, something they can think about, to help them endure their present dilemma until things get better.
(2) "... hope. It's the only thing they have."
This means they only have hope. It doesn't tell us that 'hope' is something that can be grasped, something which can be held in the mind as an incentive for maintaining endurance.
Hope can be lost if we fail to grip it, to grasp it. If we lose all hope of succeeding, if we believe all our efforts will fail to achieve satisfactory results, we will stop trying.

Weren't is a contraction, meaning were not. In a sentence it would replace were not. So since were refers to plural, it would be something like the following:The girls weren't ready to leave yet.
