How many registries?

this sunday C and i are going to be registering at Crate and Barrel, though i'm totally excited to zap things that i want that i hope people will buy for me... i'm slightly intimidated... i mean when confronted with, lets use dinnerware as an example...how the heck do you choose? and how do you decide where you register? oh and how many sets do you register for? do you register for one formal set for a "fancy shmancy pants dinner Pah-tees" set? AND one informal set for "everyday i don't care if i crack you while doing dishes" set? or do i only register for one? i feel like i need to like research high and low and read every consumer guide out there to make sure i don't get duped into getting the wrong plate! now with that said...how many registries does social etiquette dictate that you should have?

lets look at my options:

crate and barrel - love this place, very modern and stylish, has everything from home decor to kitchen utensils, but i don't think there are any physical stores out on long island...nyc folk though uber easy, SOHO! oh and they throw you a little party to register so we're all over that =P

bed bath and beyond- return policy is awesome! not to mention shoppers can use those 20% off coupons that never expire!! oh and can i also mention they have everything that you will need in your home short of the kitchen sink?

tar-jay/ target what have you - awesome prices, but terrible return policy...but they got everything and i can register for all the camping gear i'll ever need! well not that i'll camp out much (ever...)

macys - what can i say? it's macys! i can register for fancy brand things like a hotel collection duvet and ralph lauren silverware...oh and you can always find some kinda coupon that can be used here too!

williams sonoma - the holy grail of all things cooking related, everytime i walk in its like i died and went to culinary tool heaven! plus i've always coveted this slate cheeseboard i haven't seen anywhere else nearly as , as...whats the word...exquisite!

isn't she a beauty?!?!?

can i register at ALL these places? or is that like registry overkill and social etiquette suicide? i like to think three would probably be my maximum...does anyone know?
