My fiance and I are considering a road trip for our honeymoon. We've been having a lot of difficulty agreeing on what kind of trip to go on (cruise, resort, etc), but we both like the idea of taking a cross country road trip out west (we live in Pennsylvania) to see the national parks out there. I have a tentative route mapped out, which will take us to the following parks:
Mammoth Cave, Mesa Verde, Arches, Grand Canyon, Yosemite, Redwood, Mount Rainier, Glacier, Yellowstone, and Badlands
To keep within budget, we're mostly staying at campsites. Some of the parks wer're going to stay a couple days at (Grand Canyon, Yosemite, and Glacier) and the rest will get an evening and a day, except for Redwood and Badlands, which we'll only be spending the afternoon into the evening at.
We also plan to bring a cooler for drinks and food, so we can make our meals on the road (and stop for groceries along the way), which will make the trip way cheaper than if we ate out.
So I'm looking for suggestions for any cool sights that we should make time for at the above mentioned national parks. Also, if there's anything cool and quick nearby that we can stop to see along the way. For example, Mount Rushmore is right near Badlands and we can make a quick stop. Also, if anyone has any tips for road tripping, that would be great.
I'm also interested in whether you think we should make all of our campsite reservations ahead of time. Some parks have sites that are first come, first serve along with reservable sites. Reserving ahead of time means we absolutely must stick to our schedule, no matter what, but it guarantees we'll have a campsite. Doing it on the fly lets us change up our schedule if we decide we really like a certain park and want to stay longer, but there's always the risk that the campground will be full and we'll have to do some searching to find a motel or another campground (and possibly pay a lot more).
PS - before anyone asks, this road trip will be around 3 weeks
