The summer BBC Proms (or Henry Wood Promenade) classical music concerts have been performed in London since 1895. Some 100 shows are scheduled this year, most held in the evening in the spectacular circular 19th-century concert stadium, the Albert Hall, plus some al fresco performances in London's parks. The Last Night is a London event—with hundreds of Brits, many of them in fancy dress gathering at the Albert Hall, and bearing Union Jack flags for a concert of bombastic British classical music from the likes of Elgar and Parry. This year, Proms in the Park takes the Last Night party to several spots around London, promising to make it the biggest classical music party of the season. Prom concerts are easy to book: online, by telephone, or in person. To book online visit royalalberthall.com/tickets/proms.aspx. A fee of 2 percent of the value plus about $1.50 applies to all bookings, except those for Proms in the Park where the fee plus about $3.25 per ticket applies. Bookings made in person at the Royal Albert Hall incur no booking fee. The Albert Hall Box Office is at Door 12, nearest Subway South Kensington, and is open 9 a.m. to 9 p.m. daily. Book well ahead for the Last Night of the Proms as there is a very high demand for tickets. For a full concert programme take a look at the official Proms site.

Paris's Cinéma en Plein Air festival is turning 20 years old this summer and celebrating with a lineup of films that are all about life at that crazy age. From now until August 22, you can go to watch outdoor movies every night except Monday in the Parc de la Villette (19th arrondissement). The screenings begin at sundown, 10-10:30 p.m. Crowds begin to arrive as early as 8 p.m. to picnic on the giant green lawn. Travelers without access to a refrigerator needn't worry—there's a Monop' mini-grocery near the entrance to the park (at the corner of Eugène Jumin and Jean Jaurès) that sells all the necessary snacks and beverages. There are also some fast food options, a few kebab trucks, and a bakery inside the park. Admission is free, and a chair/blanket combo can be rented for €7/$9 (or 5 for €20/$26). The nights can be chilly, so consider renting a blanket if you're not warmly dressed. Films are shown in their original language (V.O.), and the following will all be in English: • July 31: Clockwork Orange (Stanley Kubrick) • August 5: Juno (Jason Reitman) • August 10: Simple Men (Hal Hartley) • August 11: The Unbearable Lightness of Being (Philip Kaufman) • August 13: Mystery Train (Jim Jarmusch) • August 14: Vicky, Cristina, Barcelona (Woody Allen) • August 21: My Own Private Idaho (Gus Van Sant) • August 22: Grease (Randal Kleiser) PREVIOUSLY Summer in Paris: The Beach Is Back

Just how much extra do you pay for the convenience of drinks and snacks in a hotel minibar? A neat new infographic from Mint.com shows you how much, using the minibar prices in rooms at The Standard NYC compared to what someone would pay for the same items in a grocery store near the hotel. In many cases, hotel guests pay three times more for the minibar goods. See the screen grab (shown in this post). The supermarket prices are in white and the hotel minibar prices are in red. Goes without saying: You'll save quite a bit by keeping your hands off the minibar and taking a stroll to the grocery store. It's a good idea to get out of the hotel from time to time too.
