Marcus,
My wife and I both have Priority Club Rewards credit cards. (Holiday Inn & Holiday Inn Express.) They have been extremely beneficial for storm chasing and we each received 6 free nights during our first year, plus another 2 nights just from the charges we put on each of our cards. That's a total of 16 free nights and they never expire.
To help facilitate free nights, we charge everything we possibly can to these credit cards, and I do mean everything. Honestly, I have no idea what our interest rate is because we always pay it off every month. There were no annual fees the first year, but we do have to pay an annual fee of $60 each year thereafter, but we get a free night every year for keeping the card. That more then covers the $60 a year fee, especially since we're getting to stay in Holiday Inn Expresses, which run from $100-$130 a night. Also, by owning this card, we automatically become Platinum Priority Club members, which gives us automatic upgrades to a better room if one's available. We also receive a welcome bag when checking in that contains a bottle of water, chips, candy, etc. And here's the best perk of all: as Platinum members, we can request a late check-out of 2pm and they will give it to you every time with no questions asked. This is huge on days where you're already in your target area or you just have a down day and only have a few hours to drive for the following day's target.
Here's the best advice I can give you for the Priority Club Rewards Visa:
1) There are lots of offers to sign up for 50,000 points, but if you hold out long enough, you'll eventually find an offer where you'll receive 80,000 points for signing up and then another 10,000 bonus points after you spend your first $1,000 on the credit card. Most of the Holiday Inn Expresses on the Plains charge 15,000 points for one night, so that's 6 free nights earned. A few charge 20,000 points, but I usually avoid these places so I can maximize my points.
2) Make sure the interest rate is one you can live with. If not, have the discipline to only charge what you can pay off each month.
3) Watch out for high annual fees. The best ones are like the deal I got. Free for the first year and then $60 a year after that, but make sure you get a free night each year for keeping the card.
And that's about all I can think of. For me, hotel credit cards are superior to airline credit cards and I've been reaping the benefits for the last couple of years.
