First, my sincere apologies for my sporadic participation lately. My life is kind of hectic at the moment and fashion and shopping have taken back seats.
I am just in the middle of the packing for my 5 days vacation. It is a girls trip, my very good friend, her daughter, my daughter and me. We are going with the car, so I am not that limited with the space, but it’s my friends car, so don’t want to pack too much either. We are going to a spa hotel in small coastal town, but weather will not be very nice, 17-21 degrees Celsius and raining. We are planning to spend some of the time in a hotel pool and wellness area, but also do some sightseeing and walking, maybe some day trips in the neighboring towns if weather allows. Dining and shopping too.
Here is what I am thinking of packing but somehow I am not sure that this is ok. Does it feel too casual? Do I need more variety? Different jacket maybe?
Any feedback is very appreciated.

You can see in the picture 4 pairs of shoes - pool slides, exercise sneakers, converse sneakers and booties. 2 pairs of jeans, 5 sweaters, handbag, 2 scarves, hat and Uniqlo lightweight down jacket. Pile in the top left corner is my pj, swimwear and exercise gear.
Will add finds later when I am not on my phone.
