We will be spending 3 nights in a cabin in Denali. We have a 6am reservation on the shuttle into the park the morning after we arrive. We realize that we will need to get some breakfast and bring lunch and snacks with us into the park. We also understand that there are not a lot of grocery shopping options around Denali. Where are there grocery stores before we get to Denali? We will be stopping in Talkeetna for a couple of hours on our way from Anchorage to Denali. Thanks!
