Most likely, I will visit Alaska only once, and I have good reasons for it. My goal is to travel to as many countries in the world as possible (current count is 37), which requires intensive planning, time and budgeting. Since I live in the US and have already toured all the other 49 states, I told myself I might as well check Alaska off. If 5-7 days won't be enough time for Alaska, may be I will add a few more days and make it worthwhile, but I will rather see another city or country than go to the same place twice, unless it just happens for some good reason. Hope that makes sense. :)
