Great thread.
I am going to share this on social media. Valet check for all!! YAY!
If valet check was available to the OP on mainline, then it should be available for ALL pax upon request (sometimes overhead bins are full when 20+ people still have to board the plane).
That the OP was held up at check-in (due to travelocity's fault) and had VERY necessary items in his carry-on for the kids is as valid reason as whatever anyone else may come up with.
I hope all GAs get the memo.
