Hey! Flying into SLC from Philadelphia on Saturday. Spending the night there. Driving to Jackson Sunday morning, staying there night there. Seeing GTNP Sunday and Monday morning or just Monday morning before the drive into YNP. Staying at Lake Hotel and Cabins in a cabin (a yellow one). YNP from Monday until Friday, so I have 4 nights to play with. Any suggestions? Already have planned to see Hayden Valley(Any idea how long of a drive from where we are? Doesn't look too far.) and the Lower falls/canyon. Plan on seeing geysers in the Southwest of the park (Grand Prismatic, old faithful, etc.) ... What else is a must see? Lamar? I also just bought a 16gb memory card in addition to the 4gb one I already have. Hopefully taking a few nice hikes as well. Thanks for any help/suggestions you might have for us. Will report back after our trip with a report and pictures! Thanks!
