I got my Chase card for the insurance--rental car, purchase protection and cancellation due to illness.
I make very limited use of the portal. I did use it to use all the points I got for acquiring the card. I booked 5 days of hotel in Melbourne. I also used it to take advantage of the hotel credit. That said, be very careful, I've noticed that prices on the portal are usually more than from the hotel directly or booking.com. For Melbourne, the hotel I chose had some kind of extra discount on the Chase portal. To use the hotel credit, I had to do a lot of searching to use it where it even made sense. I elected to use the credit on a very short stay, one or two days, so I get the credit, and didn't have to pay the inflated price for a longer stay.
Even Delta airline's portal has better hotel prices than Chase, or at least on my searches.
Its a bit of an art of deciding what credit card to use for a transaction. I use Chase for rental cars and items that I want purchase protection. I use Delta AMEX for Delta purchases, restaurants and groceries, and enough just to get me to the lowest level of status. I use Costco at Costco and when I buy gas at nonCostco stations. I use a cash back card for pretty much anything else. I also have an REI Mastercard, that we use for REI and then when we are traveling and we can't get other cards to work. And so on. .
