First, thanks to all who contribute here. I've been lurking and learning here the past few weeks as I plan our big family adventure this summer. We're moving (two kids ages 4 and 2, my wife, and me) from the Southeast to the Pacific Northwest this summer. We're planning to take about 2 1/2 weeks to get there. After a stop in Kansas to visit friends, we plan to spend a few days in the Black Hills/Badlands of SD, then on to Yellowstone/Grand Teton for a few days, then Glacier NP. I've already gotten lots of great info on things to see and places to visit from this forum.
We're making the trip in early to mid June.
A few specific questions:
-Right now we have reservations at Yellowstone's Mammoth Hot Springs Budget Cabins. That is the only thing available in Yellowstone for June. However, looking at the map, it looks like those cabins are a good ways from many of the sites in Yellowstone and too far from Grand Tetons to serve as a base. I looked at cabins outside the national parks south of YNP and closer to GTNP, but those go for hundreds of dollars per night, and money is an object for us. :) Am I right that we'll be too far away? Should I just splurge and get some expensive cabins farther south, or should I stay a couple of days on the southside (first) and then keep our Mammoth Hot Springs reservations for the last couple of days, planning to head north next to Glacier NP?
And now, availability of hotels in other places. My wife is very type-A and worried that we won't be able to find hotels when we travel. I tell her that early-to-mid June is still before the high season and we shouldn't have problems. I don't want to make reservations at all of our destinations because I don't want to run a Clark Griswold by-the-schedule vacation -- I want some flexibility to spend an extra day or two somewhere or skip something else. Still, there is a real risk of two tired, hungry, grumpy kids, and nowhere to stay (and thus a grumpy wife). That being said, are we safe traveling to the following places without reservations in advance?
-Cody, WY (a day or so there before heading into the parks)
-Glacier NP area
Thanks for any advice you can provide!
