anyone just having a cocktail reception......

just wanted to know how many brides are having just a cocktail reception for the entire 5 hours? I am having an elegant extended cocktail reception for the entire 5 hours with passing and stations....but i am confused about how to start since we are doing the entrance.....

if you are having this how are you doing it?

my reception starts at 6 and want to enter on later than 630 cause the party has to get started
