ucsun: you are undergoing a variation of a common experience, that is, the dulling of anticipation based upon experience.

Have you ever noticed that when you drive from one city to another that you find the first journey seems to take much longer than when you drive, say, for the 10th or 20th or 50th time? Why is that? More than likely, this is a similar defeat or distortion of time and distance based upon experience.

Or, as another example, have you noticed that time moves more slowly when you are younger? As we age, the years seem to fly by. Yet we know that any year (except leap years) has the same number of days. Why is this phenomenon so common? Because our memories, like our anticipations, dull with experience.

Don't fret. You will have a grand time. Just relax. Enjoy. Life is too short to be hurried.

I'll be the voice of negativity here.
A couple of times I've started planning trips and after a lot of the preliminary stuff I just wasn't excited as usual. One case in point is Alaska. It sounded great, but no matter how much research and planning I did, I couldn't get as excited as when I'm planning a trip to Greece or to Italy and France, or whatever. I figured it was just that I didn't know what lay in store. We worked to find the "best" things to do, and even went out of our way to drive the "top of the world highway" supposedly one of the great drives of the world. We lined up a couple of the very best backcountry lodges and poured through tour books and recommendations.

Well, guess what. We LIKED Alaska, but in the end, my original feelings were right. While those backcountry lodges were the highlight of the trip, they still didn't compare for overall excitement to some of the out of the way places we've stayed in Europe and Australia, for instance. And the top of the world highway just came off as OK drive, it did nothing for me compared to many of the wonderful places we've driven over the years. The whole trip was GOOD, but in the end, I think my original thoughts were right, and there was a good reason I wasn't getting as excited as usual.

Now that said, my advice is still to go and enjoy it. You won't be miserable, but make the most out of your trip. Possibly there will be things that will be sensational, so focus on those.
