Alamo and Enterprise memorial Day weekend showing blank?

Question

I had a car rental through Costco travel booked for memorial Day weekend. I checked to see if prices got cheaper and now enterprise and Alamo are just blank for all vehicles, only avis and budget showing. Anything weird going on? Or maybe just sold out?

Answer

It’s not uncommon to see Alamo and Enterprise showing blank or unavailable for certain dates, especially around busy travel periods like Memorial Day weekend in Hawaii. There are a few reasons this might be happening:

Sold out: Kauai, like other Hawaiian islands, has limited rental car inventory. Popular companies like Alamo and Enterprise often sell out months in advance for peak holiday weekends. If prices were checked recently, it’s possible all their available cars were already booked.
Inventory blocks for partners: When booking through third-party platforms like Costco Travel, not all cars are shown if the rental companies reserve certain vehicles for direct bookings or other travel partners. This can make it appear as if they are “blank” even if some cars exist.
Technical glitch or website issue: Occasionally the rental sites or aggregators experience temporary glitches showing no availability. Refreshing the page, trying a different browser, or checking directly on Alamo/Enterprise websites can sometimes resolve this.

Practical steps you can take:

Check availability directly on the Alamo and Enterprise websites for the same dates. Sometimes the company’s own site has cars that the third-party site doesn’t display.
Try adjusting pickup and drop-off times slightly. Even shifting by an hour or two can open up availability.
Consider alternative nearby locations (e.g., Lihue Airport vs. town offices) if flexible — some local branches may still have cars.
Book as soon as possible. Memorial Day weekend is very high demand, and once vehicles are gone, there may be no more options from these companies.
Keep other companies like Avis, Budget, or local rental services as backups if Alamo/Enterprise remain unavailable.

In short, it’s most likely either sold out or inventory reserved for direct bookings, rather than anything unusual. If you already have a booking through Costco Travel, your reservation is secure — just try booking early next time for peak holiday weekends to avoid this stress.
