Any given package will have its own set of little perks, and those should be explained wherever you're thinking of booking. Check those out and figure out if it would be of value to you.
It's always important to find the TOTAL cost, including taxes, etc, for all the options of any trip you take; sometimes a package turns out to be better, and other times a la carte works out better (especially if you're thinking to ultimately get an AP and there are AP rates during your intended stay). You just have to work it all out, do the math, see if the perks are worth it, and book as soon as you find a price you like! (I once waited, and literally overnight the prices shot up. that was not fun. book when you find the price. don't wait.)
