While in YNP, we WERE staying:
2 nights OFI
2 Nights Canyon/Dunraven
1 Night Roosevelt Roughrider
but... I just swapped one of the nights at Canyon for a 2nd night in Roosevelt! Tell me I made a good decision. I really don't like being without a bathroom, but I wanted more opportunities to see wildlife.
The only other thing was we originally had 3 beds at Roosevelt, but when we added a 2nd night, we had to switch to a 2 bed cabin. Oh well...
