alaska trains - which option?
 

we'll be traveling from Denail to Talkeetna by train and are wondering if we should go with the regular (adventure class) train, the GoldStar Dome service or the Wilderness Explorer, which runs at the rear of the trains and has the domed roof. We will be taking the GoldDome service from Anchorage to Seward later in the week. I am wondering if the upgrade to GoldStar on the Denali to Talkeena leg is worth it? Or maybe just the Wilderness Express might be a good mid-range option. Anyone have experience with this?
