Translate shield?

Hello guys,

I will travel to Japan in about 2 weeks and we're planning on renting a car for a one day trip to Mt Fuji. We have to park the car after our trip overnight though and I looked through street view if there were any parking spots near our hotel and found this one. Can someone translate what's on the shield and could tell me approx. how much it would cost me?

Within 12 hours, 2500円(Approximately 22usd)

Bottom left word,
追加料金（additional fee）？
通常料金（Regular price）？
I can not see the picture well.

Be careful !

On Sundays, national holidays and from 31 December to 2 January,
Within 12 hours
Maximum fee 2,500 yen

Regular fee 8:00-22:00 22:00-8:00
100 yen/12 minutes 100 yen/60minutes

Just curious. Doesn't your hotel offer parking space for a fee? You can't reserve the kind of parking lots that is shown in your photo.

Thank you guys, so within these days, it would cost me 2500 / 12 hours.

And no, it's a hostel and they don't have parking lots. I will switch to another hotel after 3 nights, but there, a night costs 3000 yen, which is a little bit too much imo. This way, I would pay 1000 yen from 22-8.
