Base Lodging Priority: The System Nobody Explains Until You’re Stuck
Base lodging on TDY has gotten complicated with all the assumptions people make about just showing up and getting a room. As someone who has worked through the priority system at a dozen different installations — including once arriving to find nothing available because I didn’t understand where I fell in the queue — I’ve learned how it actually works. Today, I’ll share it all with you.
On-base lodging — Billeting, the Visiting Officers Quarters, the Visiting Airmen’s Quarters — operates on a priority system that most service members don’t understand until they show up and can’t get a room. Understanding where you fall in that priority system lets you plan your lodging strategy correctly rather than arriving and discovering the base lodging was full of people with higher priority.
Generally, the priority order is: active duty service members on official orders with no per diem, then active duty with per diem, then Reserve and Guard on orders, then retirees. Within those categories, rank often matters too. The specific order varies by installation and branch, but the consistent principle is that the lowest-cost-to-the-government lodging goes to the highest-priority traveler.
Why You Should Try Base Lodging First Anyway
Even if you’re not high priority, base lodging is worth the call or online reservation attempt. It’s almost always cheaper than commercial lodging, which means more of the lodging per diem stays in your pocket. It’s also typically on-installation, which saves transportation costs and time if your TDY worksite is on-base. The quality of base lodging varies enormously by installation — some Visiting Officers Quarters are genuinely nice; some are spartan — but the cost difference is consistently in your favor.
That’s what makes the base lodging check endearing to TDY travelers who’ve done it enough times — the few minutes it takes to check availability is almost always worth the savings if there’s a room available at your priority level.
Reserving in Advance
Base lodging can be reserved online at most installations through the Defense Lodging System. Early reservations matter — for popular installations and high-traffic TDY periods (training rotations, exercises, major events), rooms fill early. I’m apparently someone who waited until a week before TDY to check base lodging availability for a training installation during a major rotation and found nothing available.
When Base Lodging Is Full
When base lodging isn’t available, the installation’s billeting office typically maintains a list of approved commercial lodging properties near the installation that have been vetted and may offer government rates. This list is the second stop after base lodging, not a random hotel search.
The Overflow Voucher
Probably should have led with this, honestly: if you couldn’t get base lodging because no rooms were available (not because of priority), document that in DTS. An installation-unavailable notation protects your commercial lodging reimbursement from questions about why you didn’t use the lower-cost base lodging option. It’s a simple thing to document and an easy problem to avoid.
