The Premier card is really good if you charge just about everything to the card and then pay it off monthly. And also if you have a lot of charges in the bonus categories. But if not, I would stick with the regular version.
For us, it is perfect. I charge everything to the card (including utilities, etc) and then pay it off every month. We are DLR APs so we have many Disney charges. Our monthly AP payments are on the card, we charges our meals there, etc. We also have been doing a lot of Disney cruises lately.
I upgraded my card towards the end of February and I have already earned an extra $277 in rewards due to 5% bonus promotion (with another big payment towards a cruise coming during the promo period which should earn me another $100 rewards for just that one transaction). So during the promo period, I have covered the first 7 years of annual fees. Now all the extra 1% transacations (meaning the categories that I earn 2% instead of just 1%) are just icing on the cake.
