I was trying to post this earlier but the connection was continually timing out... [good job I now draft any longer replies in e-mail!]
You lucky lucky 'bar-steward'!
From a Brit view-point...
Paris. We have that 1,000 year old 'friendly rivalry' thing going on. So ask a Brit and expect responses to vary. The first place most young Brits go abroad might well be France, likely Paris, hence for most adults it can be a bit 'Been there done that (several times)/sigh'. The French can have a reputation for being quite snobby, and in Paris it can be haughty verging on in your face rude. I'm not saying that'll be your experience, but that's how a typical Brit might see it. Example: Someone might be fluent in English but they'll refuse to speak anything but French, esp. if you're English. Then they'll laugh at your schoolboy level of French... love/hate
But there are some things you should do. Have a look at TripAdvisor for their ranked suggestions, and LonelyPlanet too. Things like the Eiffel Tower, Notre Dame cathedral likely come out in the top few.
Many visitors seem to have a drive to see the Mona Lisa. Well I don't know. In a way you might consider the frenzy it creates more of an interesting thing to witness.
Go to the meat section of a supermarket and stare in wonder at some of the weird stuff they eat
Horse, sheep's brain, frogs legs, snails, and so on...
Do some precautionary reading up on how cafes charge, as it used to be very confusing. Example: Walk into a cafe, order a coffee, get handed the coffee and take it the counter by the window and sit and drink it and it costs X, but if you sit outside at a table and a waiter takes your order and brings it to you it used to/still does? cost considerably more, plus the waiter will expect a tip. Understanding this is especially important if you happen to be in a touristy area (esp the main-drag of the Champs Elysee etc) where it's notorious for tourists to get stung even say S$50 for sitting outside a cafe and having a coffee and piece of cake.
Again from a Brit-perspective... Budapest.
Worth reading up briefly on the history before going, as it'll give useful context for what otherwise might be a place not so simple to immediately understand. Became very powerful and wealthy right through to WW1 - hence some amazing architecture that remains etc. Got invaded and/or annexed by both the Germans and Russians. Was part of the super-powerful Austro-Hungarian empire, and so on. Was communist/'Eastern-block' until independence in the late 80s. This was around the same time as the fall of the Berlin Wall etc...
https://en.wikipedia.org/wiki/Hungary
Hungary have now understandably had enough of external rule by others, so they have a somewhat arms-length relationship with the EU. They are a member, but they have their own currency, the Forint. Similar to how the UK retains the Pound, and for many of the same reasons.
When I was young Hungary wasn’t a place I could have or would have chosen to visit. It was closed, then had a lingering ‘commie’ taboo hanging over it. Now with budget airlines it’s being rediscovered, esp by long-weekenders visiting Budapest. So your experience can be one pitched at such fast-money, but do a bit of reading up and the real Budapest is not hard to find.
As it happens we visited just 6 months ago, and found it to be really great. It has a huge old castle, cobbled streets, street-markets and so on. There are loads of city river cruises which is a nice lazy way to see some of the core buildings and districts and hear the historical context given. Summer is the best time to go, it got pretty bitter in winter I can tell you! Paprika is the star food ingredient in Budapest, so go and seek a great offering of beef/other stroganoff (spicy meat or veggie stew, it’s like 1/2-way to a curry
).
You can spend hours browsing in the street markets. Lot’s of offerings like sausages, beer-stalls, fresh funnel-cakes... no end of F+B options, plenty of veggie options too. There is an awesome historic cake/ice-cream shop on the main square too, my wife+SGn visitors went nuts there Smile
Again do a bit of background reading on TA and LP. I’d happily return at the drop of a hat.
If you’re not being picked up at the airport, you need to figure out how taxis work. IIRC you need to go and buy something like a taxi-coupon from the proper booth, if you take a taxi and pay the cash fare you might find a few extra zeros on the end. ps. Some great beer there too, worth researching a short-list on Beer-Advocate!
