mmmgvsb's Green wedding

I will be having a shower and a bachelorette for the wedding.

the 2 stags for myself and the one for my fiance we ahev no clue what is being planned. Our Job is to show up that day, the bridesmaid along with my MOH will be planning mine and for my fiance his groomsmen along with his BEst Man willbe planning his.
I'm nervous have no clue what my girls are up to.

For our bridal shower we do know what is going on, I'm really into the planning for everything so they all agreed that I can help do the shower. My Maid of Honor will be the Host for the shower, and one of my cousin and her husband had asked to cater all the food and booze. Which is a very generous offer from them. A BIG THANK YOU.
The theme we have decided is the Polynesian theme (pretty similar to a luau) My background being Polynesian it will be so easy to pull this one off. Some of the Decor we already have and just to buy little things here and there. For every womne that enters into my parents back yard that day will be honored with a Lei and alot more goddies for them.

I have ran by my fiance about getting registered at a store for the shower, that way everyone wont be asking "what to get the couple" My fiance thinks the idea sucks. he feels we are telling people what to buy, I don't though. I think it's better to give everyone the idea of what we need then to get something that we wont need. Weve been living together for a while now and we do have some stuff already, I think I will save everyon';s time.

Is it wrong to register????
