Short or Long First Dance?

IDK what the standard is but ours will be about 4 minutes

Short. 2 minutes of our song max.

We are doing the entire song. It comes out to about 3 minutes.

We're considering shortening our first dance, or at least having our guests join us have a minute or two, so we're not the center of attention the entire time.

Shorter, we are doing a first "serious" dance for our favorite verse, bridge and 2 chorus and then surprising our guests with a little piece from one of our favorite movies, No not dirty dancing or grease lol .

Probably short. We haven't decided on the song, but all the ones we like are realitively short.

Long. We're doing a mashup of a a love song from 1985 when we first dated into a more current one

We haven't picked a song, so I guess it depends on how long the song is, but I would prefer to dance for the whole song or have the DJ ask other couples to join us after the first maybe 2 minutes.
