The Hyatt hotel family includes the Hyatt-name brands (Park, Grand, Place, Regency, and House) as well as Andaz. Its network is large and international, but not quite as extensive as the biggest chains. Their points are more valuable than all other chains except Starwood, with their top-tier hotels going for 22,000 points/night.
Suites only cost 50% more points than normal hotel rooms, so if you are into quality over quantity, Hyatt may be your match. Hyatt points can be obtained by transferring at a 1:1 ratio from Chase Ultimate Rewards points. This may be a good deal, given how valuable Hyatt points can sometimes be for redemptions (for example, some 8,000-point hotels retail for $300+ per night).
The easiest way to get a nice stay at a Hyatt is to apply for the Chase Hyatt Visa, which gets you 2 free nights at any Hyatt in the world after spending $1,000 within 90 days. So let’s look at the Park Hyatt Maldives as an exotic example, where rooms go for $650/night. Or the Paris Park Hyatt Vendome, where rooms go for $900+. I would highly recommend getting this card if you are going to Paris or another city that hosts an upscale Hyatt–the only reason I have not yet gotten the Hyatt card is that there are too many other amazing Chase offers out there and I can’t overdo it with too many Chase applications at once.
