Lost a close friend whose service is on 12/27. When looking at tickets some offer a discounted price 'with restrictions' but no details until after entering all of your information. (Last minute Christmas weekend tickets are high as would be expected.) Has anyone tried this? Is it safe? Are you locked in even if the details don't fit your needs? We are advanced planners normally so this is new to us. Thanks in advance to anyone who can provide their experience.
