Trying to make a decision soon…I am booked for the Britain and Ireland tour departing Sept. 2 2012 but it’s not a guaranteed departure yet. I haven’t booked my flight yet because if I have to change it I don’t want to lose money but at the same time, I don’t want to wait too long to book it either. I was thinking of switching to the tour a week before because it’s already a guaranteed departure. Should I change my tour date or should I wait it out to see if the one departing Sept. 2 becomes guaranteed? And am I even able to change the date? Thanks for any advice!
