No. Entrance to the cemetery is no cost.

There is a fee to go into the cemetery. The changing of the guard is a short walk away. You do not have to get on the tour trolley, however once you have paid the entrance fee why NOT take the trolly. It is included. I do not think you can go in otherwise but I am not sure as I did not inquire. Sorry I could not be more helpful.

Hoooooola. La entrada al cementerio es gratis y no debes pagar nada si fueras recorriendo x tu cuenta. En caso que no desees caminar hay un trencito que es pago y te lleva a recorrer el cementerio que es muy grande en extensión y es increíble la cantidad y diversidad de tumbas. Esta dividido por sectores : 1ra guerra, 2da guerra mundial, guerra de corea, etc etc. Puedes llegar en subte y si vas en auto te cobran el estacionamiento por hora. Espero lo disfrutes.

Free parking is nonexistent on the East Coast in general. If you are on a timetable, bite the bullet and park at Arlington.

I would research directly with the visitors center on site. You may need a special pass or invitation and possibly security clearance in this day and age. If you are staying nearby at a hotel, a hotel concierge may be able to assist you. All the best.

It's about a 10 minute walk depending on your pace. Just note that it is kind of steep so have good walking shoes and drink water as it can get hot

Yes, I took lots of photos - assume you could video too

No, it's free and if you go to the visitor's center, they have guided tours via trolleys and you can get on an off at the most popular sites. Highly recommend it!

Front row and towards the right facing the guards so you have a good view of them entering.
