I just bought my plane ticket! It was a little more stressful than it should have been, but when you are spending so much money on one thing it's to be expected. I purchased an ISIC card as well which will give me discounts to museums and historical sights among other things.
I'm expecting the before travel parts of my trip will be the most stressful. Getting on the plane will be stressful because I have never gone through that process before. Then after I arrive in London I have to get transportation to Bath which I expect will be a stressful experience as well. See, it isn't the actual travel that I worried about. It's the before and after. The traveling part is just sitting and being bored of staying in one place is not stressful.
I will be arriving around 8 am so I will have time to play with to get everything arrange. Research will have to be done on where to purchase tickets so I am not a bumbling around like a fool.
