Wait 'till mid- September or later fly one way and take a repositioning cruise home
Norwegian has one from Rome for $750 or so.
I much prefer avoiding cities like Paris in the summer...in the fall the opera, symphony and all gear up and some (at least) of the tourists are gone.
So many other cities (in France, Spain, Italy) are wonderful and much calmer...for example
we visited Pisa in early May...the area around the leaning tour was jammed.
The rest of the city was mostly locals...we loved it
Hotels?
Seriously, the most amazingly beautiful city in the world and I'm writing this from Vienna which ain't bad either.
West End Hotel, 7 Rue Clement Marot, couple blocks south of the Champs Elysees on the Arch de Triumph end. They speak English. Rooms are $275-350 depending on what days/season. Modest but comfortable, continental breakfast included. Location is primo - walk everywhere.Hotels?
+ 1000 for everything here, esp. how you think of shops and their owners. You are visitors and their guests.You can get a variety of 'city cards' (do this in any European City - they are generally well worth it) they get you into museums and attractions and usually provide a separate entrance process that avoids the lines (especially important when traveling in summer.) The duration of the card can vary from a single day pass to a week or longer, some offer free transit on buses and subways and even regional trains and if you do even moderate tourism they are cost effective, especially when you add in the time not waiting on lines.
My favorite two museums in Paris are the Rodin, and the Musee d'Orsay (there is an amazing view through the clock face of the Basilica in the distance from one of the upper floors.) But there are so many great museums in Paris many devoted to a single artist, often in their former homes or studios. Monet's gift to France following WWI of his waterlilies cycle displayed in the Orangerie can be as moving as the graveyards in Flanders. And a visit to his country home and gardens Giverny is an easy day trip from Paris - as are the various royal palaces including Versailles.
If you like mussels find a Belgian restaurant as they are famous for them - even places like the Champs have a good one Leon de Bruxelles. The Parisian parks and gardens are wonderful and a great place to picnic with fresh bread, cheeses, fruits, etc. picked up at the great little shops around.
One thing I was told the first time I went to France and I think is very important - whenever you enter either a shop or restaurant (or even your hotel) start by acknowledging the proprietor/waiter/etc. with Bonjour or Bonsoir (evening) - we Americans tend to enter a shop and immediately get to the point with 'I want ...' which is insulting to especially the French but many Europeans - they are there to help you, not serve you. You are likely to get better service and a friendlier reception.
Exactly what I would have writtenI've done it twice from Boston. Lots of airlines to choose from, tremendous variation in price. One thing you might consider is Icelandic Air is often pretty cheap - and, they had a deal where you could work a lay-over in Reykavik, and spend a little time exploring Iceland, which is really cool. August in Paris is to be avoided, if you can - practically the whole country goes on vacation, the lines are long, prices are up, and it's the month for the traditional strike for trash-haulers and train workers.
Oh, and Charles De Gaulle airport is awful. Tough to avoid, as it's the main international hub, but, man, it takes forever to taxi in from the runway, get from one gate to another, get through customs, etc..

I envy the Prague. Never been and I hear it's spectacular. Staying in Vienna just above the ring road. The whole city is overwhelmingly beautiful. Heard some nice music but the opera isn't in season. That's a must. We toured the opera house today--magnificent. Even if you aren't an opera fan, that's the single most Viennese thing to do.I'm doing Prague and Vienna in late September. What part are you staying in?
