We've been going for about the last 20 years. Used to always book a package. What we found was there wasn't really a lot of savings and the packate cut out some of the perks the hotel would give you. This year we booked seperate and ended up with more perks=better deal.
Bottom line each airline/hotel is different so price it both ways to see what is the better deal and check the perks i.e. coupons, room upgrades etc at your hotel you might be surprised.
