bridal shower ?

Hey ladies
I have a shower to go to in september in NJ on a sunday ...
its at a resturant... how long does it usually last? and it says wishing well on the invite.. that means get one of the little things off the registry too or something little i 'think' they need ( i hope its a registry thing haha)? does that need to be wrapped as well as the gift?

(im the first one of my friends to get married ... and this is a shower of FH's friends fiance)...

TIA!

Showers last 3-4 hours (at least all the ones I've attended have).

As for the wishing well - find out the theme. The buy a present off the registry to fit the theme, or something they could use. It can be wrapped, or it doesn't. Completely up to you.
