DH and I returned from Anchorage 10 days ago. The place is beautiful and I would highly recommend everyone going. However -- we soon found out that a lot of tourist attractions in Anchorage close down in mid-September. Several restaurants were closed for the season. We did find one place that was still offering one-day glacier tours. The tour and the three hour bus ride to Seward were great, but that tour had been cancelled for over a week before our trip because of bad weather. With the exception of taxis, there is not a lot of public transportation. Several touring companies offer bus transportation but, again, most of those were closed.
We hope to go again someday, but will definitely go before September 1.
