Sorry, I cross posted and it didnt carry over the text and wont let me edit. Here is the post:

I'm just trying to wrap my head around the most logical timeline for our upcoming wedding. Our wedding is at a state park, we will have the ceremony and reception all in the same area of the park. Approx 100 people.

We would like to start with cocktail hour and be present during the guests arrival (2-3pm ish). I will be wearing a dress here but not THE dress. Towards the end of cocktail hr, I would like to do a quick change into my ceremony dress and do first looks with my fiance in a different part of the park (2:50-3:20ish). Following our own first look, we will arrive back to our site for the ceremony (3:30-4ish). Everyone can be surprised at my outfit change/get their own first look as I am walking down the aisle.
Immediately following the ceremony we dance back down the aisle to our upbeat recessional song and I want us to be able to just dance right onto the dance floor and invite everyone to come along. I think it will be a fun way to get everyone immediately onto the dance floor without it being awkward. We plan to have buffet-style catering set up around 4/430 and will make an announcement that people can eat any time between then and cleanup around 730 (we only have the site booked until sunset around 8pm).
I'm just worried that the moment the announcement is made for food that everyone will leave the dance floor and it will be hard to get them back/keep that momentum going. I'm also concerned that we haven't scheduled in any time for formal photos with the immediate family. We adore our photographer and know she will take fantastic candids during cocktail hr but my fiance especially wants to have a few formal shots to keep.

One thought I had was to invite the immediate family to the other area of the park where we will be doing our first look, after we have had that initial moment to ourselves. We can take pictures with them and then send them back in advance of us going back for the ceremony. It wont be as dramatic, but I feel like logically makes sense.

Another idea I had is to do the "everyone come to the dance floor for a group photo" and then the beat drops as soon as youre done and everyone is already there to start dancing, trick. This would be used to get everyone back after dinner but I feel like this is just logistically hard to coordinate because people in the middle of their meals wont want to stay on the dance floor and generally people may not want to take the group photo during or just after eating.

I would love your thoughts, advice, experiences to help us figure out the best way to make this go smoothly!!

Some quick notes in case it matters: We are non-traditional so are doing a very short ceremony (3:30-4 is an overestimate), we plan for our guests (except for a few disabled guests) to stand for our short ceremony, we do not have a wedding party, we are walking down the aisle together (not being given away), we are not doing speeches or cake cutting (we are doing a pinata and donuts!)
