Not much time left
The Bridal Shower is for the "Ladies only" and the grandmas and close friends attend, now the bachelorette party is different it's usually a drunken affair
and most of the time the same night as the Bachelor Party. You could combine the two depending on the group you have.
Yes you should plan these parties
So I think you need to get busy with the speech LOL, J/K the Best man does the main speech, but you can too if you want. You should do one at the Bridal Shower.
It the brides & her Mothers responsibility to do allot of that other stuff.
GOOD-LUCK
