tl;dr – Helpful (I guess) if you’re chasing Allways Rewards.
Allegiant Airlines recently partnered with Rocket Travel by Agoda to launch a global hotel booking platform enabling travelers to earn Allways Rewards for their hotel stays.

Rocket Travel is essentially the white-labeled version of Rocketmiles – the original consumer-facing hotel booking site for earning miles when you book stays. Rocket Travel powers the hotel booking platforms for several airlines, such as American Airlines (AAdvantage Hotels) and, recently, WestJet (WestJet Hotels).
My travel patterns don’t overlap too much with Allegiant’s footprint, so I haven’t had much of a need to pay attention to Allways Rewards. That said, more opportunities to stack loyalty points are a good thing.
