Courtney, good luck to your daughter on the bar exam! I still remember taking it—2 1/2 excruciating days of mind-numbing questions on a metal chair with a flat cushion. I'm sure it's a little different now, and I think it's all online but it is still mind numbing, lol! And then you have the agony of waiting for three months until you get the results. 😂
So I'm sure she will be ready to let her hair down and get out and travel! Good for you for taking her! I'm taking my daughter to Iceland, Sweden, and Norway for three weeks this summer to celebrate the end of her first year of medical school, so I get what it's like.
At any rate, I agree with Stan in that I would say going to London, Paris, Normandy, Rome, and Venice would definitely be a 3-week trip. If you need to cut it back to 2 weeks, then I would suggest skipping at least one, if not two, cities. Going in August, and I'm assuming that's when you are going, can have some advantages in that many locals in the cities head out of town, especially Paris, during that month, so it would be less crowded. If you wait till September, Paris gets more expensive, so there's that as well.
Going on a tour would probably be easier, and if you're averse to doing all the planning (and it sounds like you would be the one doing the planning), you might want to think about that. But then again, I'm a 71-year-old woman who's traveled solo to Europe for over 30 years, I do all my own trip planning, and it's not too terribly difficult to plan everything. In fact, I enjoy it, but that's me. If it sounds like a pain to you, then I would suggest looking at some of the tours listed above.
But really, since you're staying in cities and I'm assuming you would be traveling by train or flying between each city, it wouldn't be that difficult to plan. You just need to book flights and hotels for the most part, and then some of the attractions need to be booked ahead of time, like the Louvre in Paris and so on. But you've got plenty of time to do that. Although you don't want to wait too long for popular destinations, it's good to book at least six to nine months ahead of time if possible. That gives you the best hotel choices in the best locales with the best price. 😊
If you decide to do the planning on your own, please come back here for help. We all love to share information (sometimes too much, lol!), but we really like helping travelers plan their own trips or find a tour if that's what floats your boat. We can recommend hotels, and if you need a flight, we'll tell you where to look.
