Hi Bob
I'm glad you had a good time in the States.
The new brochure won't be out until late May / early June and I don't think we'll know what next year's dates are until then. So unfortunately, I don't think you will be able to wait until then to use your voucher.
You might want to try giving our holiday advisors a ring on 0844 567 8844 to see if there's anything they can do for you.
Kind regards,
Olly, your editor
