Is there a limit to what you can request in regards to a reenlistment ceremony?

You can request anything you like. Whether your command is willing to entertain it comes down to how you arrange it. The Army is not going to fly your spouse back from a rotation or fund your travel to a different location. But, if you take a 4 day pass when your spouse comes back and travel to the Grand Canyon with your reenlisting officer, that would be a normal request.

Each of your requests sounds reasonable and seem like they can be accomplished. A re-enlistment ceremony is meant to be special and memorable. Only advice I would give is to ensure that any request you have should take into consideration how to best honor the act of re-enlistment. It’s a time honored tradition and must remain sacred. As long as you don’t dishonor the meaning and significance of the ceremony, you will be okay. An example of a “bad” re-enlistment was the Airforce NCO who executed the oath of enlistment using a sock puppet, I don’t recommend doing that. Congratulations!

I assume you are active duty, the military cannot put an expense behind your re-enlistment. You can always request guests (at least those that can gain access to the installation), Family etc. As for your spouse returning from a distant assignment or location, maybe, if they are within travel distance and a pass will not interfere with official requirements. As for other states etc. not at all likely unless your installation is a stones throw. Too many variables, I hope this provides some insight. Thank you for your service.
