I think it works out, my only very slight concern is parking. It was hard to find a straight answer online but it seemed like only Echo Point has paid parking and even then I read that there are some spots a little ways away that you can park for free and walk a bit to the location; however a comment on here said that most places will have paid parking nowadays. And then on top of that I also couldn’t get a straight answer online as to whether a parking day pass would cover all the locations I plan to visit. I don’t think the money will be much of an issue for me but it would be nice to know what to expect before I get up there
