I’ve probably had my share of Liner moments - as well as my share of fails. 
I know my wife appreciated when I scored CBR for a net daily rate of $75 on one trip due to nabbing the latest discount and them stacking a construction rebate on top.
I know my kids appreciated when I took advantage of a FPP tier glitch one year and was able to book multiple Tier 1’s in EPCOT one day.
I think my recent favorite, now that my kids are older and I think more aware of tactics was when we went to MNSSHP 2 summers back. About 35 minutes before the parade was set to come through, I walked my family up to a spot in the hub and shifted them over until they were exactly where I wanted them to be.
I could tell my son was giving off the “what’s the big deal with this spot vs the one I randomly stopped in, dude?” vibe. But then a few minutes later some CMs walked over and installed poles and ropes right next to us, then made everyone else move back behind a line in the pavement.
I pointed out that spot meant NO ONE could be in front of us or even next to us- and the parade would slowly work around the hub and come RIGHT at us. Great for photos! They were suitably impressed.
