I'm a "funeral home kid", which just means that my grandpa is a minister and he managed a funeral home for my entire life, until he retired. He and my grandmother even lived upstairs above it for several years.
I've been around bodies and the funeral home for more services than I could even begin to count.
My best friend's family owned the other funeral home in town, so I have just always been around it no matter what! I have a very different attitude about the dead, and death and dying in general, that most people I've met (including my husband, who has limited experience with death and/or funerals) have trouble relating to.
I've probably seen it all, including one service where everyone in attendance was wearing Hawaiian shirts and had a Jimmy Buffet sing along. That was also my favorite.
Most people do the traditional viewing (usually called "family night" around here) the evening before for a couple of hours, and the body will lie in state at the funeral home for a day or so, so people who can't attend the service can come sign the guest book and pay their respects. Then there is the funeral service itself, either open or closed casket depending on the family's or the deceased's wishes, followed by internment at the cemetery, typically referred to as the "grave side service". Many families elect to have only a grave side service if cost is an issue, and they are not comfortable with cremation.
My family tends to skip the viewing/family night part when our own people pass away, simply because it's usually worse than the funeral itself in terms of the sadness factor.
Personally, when my own time comes, I would like to be cremated. No service necessary, unless they choose to do a "celebration of life" type of thing. Maybe I'll ask for Hawaiian shirts and Jimmy Buffet

That'd be a good way to ride off into the sunset.
