The Big Bus folks were at the Princess cruise terminal in Whittier to pick us up. The bus was full and there was a seat for everyone so do pre-reserve your seat. I did it all on the Internet. Of paramount importance to me is always safety on these buses. The driver was very professional and safe. He kept his eyes on the the road whilst a guide did the talking and narrating as we went along. We took the tour that stopped at a glacier outside if the tunnel and for about 45 minutes at the wildlife center. We were at the airport by 12:30pm. They will also drop you at your Anchorage hotel. I highly recommend them and would use them again for sure. About half the price of Princess doing the same transfer and just as easy.
