Cocktail hour?

Guess it depends on the venue. I've been to weddings where the cocktail hour was in the reception space. My venue has a separate area for cocktail hour and reception which is separated by the bar area.

It's absolutely fine to have the cocktail hour and reception in the same space. The cocktail hour is typically held in a different space when the ceremony space needs to be flipped into the reception space (which occurs during cocktail hour), but that's not the case here since your ceremony and reception spaces are different

Four Weddings is not accurate for most weddings. But many venues have one room/space for everything. Everything takes place in place in one spot and no blinks. Even for appetizers, you need to have tables/chairs for everyone, in addition to your assigned seating. It will all work out.

We doing our cocktail hour out on on the patio at our venue

It depends on your venue. I have been to several weddings were cocktail hour was held in the same space as the reception. However, for our wedding our cocktail hour was held in a separate space.

Our venue really only had 2 spaces. We used the main space for ceremony, the cocktail hour was in the 'lobby' area as they switched over to reception, and as soon as that was done, the cocktail hour was allowed to spill back into the main space.

Please don't use TV shows as a guide. You'll just frustrate yourself.

My ceremony, cocktail hour and reception is in the same venue space!!

It depends on your venue, but if it works you can definitely have the cocktail hour in the same area as the reception. We're getting married in the garden area of an athletic club, with an attached pavilion and a deck up one flight of stairs. The pavilion will be closed during the ceremony and all the tables for the reception will be staged there. Once the ceremony ends, the guests will go up to the deck for the cocktail hour while the staff moves the tables out from the pavilion and we finish up our pictures. Once everything is set up, guests will move back down to the garden area for the reception and the pavilion will be used for dancing.
