Is a one hour time gap between ceremony and canapes ok?

We are looking to have our ceremony at 3pm, and then canapes to start at 5pm, this means there will be a one hour gap from 4pm-5pm. Looking to have both the ceremony and reception at the same venue. Is it acceptable? To entertain guests, there will be a photobooth along with a few platters of snacks, and a bar tab on soft drinks and coffee/tea. Alcohol will be available at 5pm once canapes start. Or if they prefer, they can explore the venue gardens and take some photos.
