I have been to Anchorage in excess of 35 times or so. I have stayed at the Sheraton at least 10 of those times. Pluses... Easy free parking, nice views. Minuses ... not "quite" as close as you might want to walk to eat and such... but I prefer it over the Hilton. I don't like staying by the Airport. You may want to spend one of your nights down in Seward (about 100mi s), or at least at Girdwood (Alyeska Resort - about 45 mi s). Hotel prices are outrageous for what you get, but often the nice hotels (ie, Sheraton) are only $20 more than the Days Inn, which in ANC is a dump right across the street.
