The motor coaches for the land tour leave in the morning from the dock in Seward. You would need to find out what exactly the itinerary is for the first day of the land portion. Some don't stay in Anchorage but go all the way to Denali.
There are restaurants and shops within walking distance and also a free shuttle. Seward is a small town and easy to get around. They are known for the murals around town. They also have a SeaLife Center. You can Google that.
