Some thoughts which will be helpful to travellers to Nice and France as a whole:

 1. Forget car hire on the Riviera! Traffic and parking is a nightmare everywhere you go and unlike most other popular holiday destinations, car hire is expensive. It's about £40 a day and then another £10 a day for CDW Insurance and then a heavy deposit on your credit card. With the exception of Grasse (station is about 1mile from town centre) every station was within 5-10 mins walk of the centre of town and fares were very reasonable. Buses are exceptionally cheap 1€50 for any journey up to 70mins but they are crowded and a mix of warm people on a crowded bus is not for everyone!

2. When using train travel DON'T be tempted to not travel without a ticket, and don't be tempted to ride the TGV trains without the required reservation (wait for the next ordinary TER instead).  Most stations, particularly small ones are unmanned and there are no checks on the trains themselves but be warned! The SNCF have their own police who operate ticket checks with station staff in purge operations to clamp down on non-payers.  It's a 50€ on the spot fine regardless as to whether your a tourist or a local. It's tempting not to bother but for the cost of a ticket (Nice-Cannes 9€ return), it's not worth the risk. Trains have much more capacity than in the UK as even the TER trains are double decker so you'll always get a seat and all the carriages have air con. But beware, unless you are intending to visit the massive weekly market, do not travel in the direction of Ventimiglia on a Friday morning when the trains will be packed. Finally - the French railway unions seem to love calling random strike action so it's worth checking on the internet first before you travel

3. On arrival at the airport, if your hotel is near a station, take the train. Nice St. Augustin is a 10min walk from the station but you won't find it marked as the Airport Station and most guides will tell you to take the express bus to Nice Ville Station but that's 6€. Therefore, save yourself 6€ and get on Shank's Pony - it is marked with signs but if all else fails, Google Maps on your mobile will get you there (don't forget to turn off data roaming when you've finished).

4. Taxis are extremely expensive from the airport, because the taxi drivers are required to pay an extortionate sum for the right to ply there - something like 250,000 euro for airport rights. In return they are obliged to operate a fixed but generous tariff which makes it worth their while - nearly 50€ for a taxi 5miles from Nice Station is normal, Cannes is over €100 and St Tropez over €250 . Business travellers on expenses mostly don't care, but the budget traveller should think of taxi's only as a last resort. Nevertheless there are plenty of taxis queing up, patiently waiting their turn for the next traveller. A short hop means they lose their place, so will generally be met with polite refusal.  

5.  On your departure to the airport, don't leave it till the last minute! The airport is very busy and operating at a very high capacity for the size of its terminals so queuing at check-in seems normal, but Easyjet now offer bag-drop (and of course online check-in only) which has speeded things up. And queues at security are sometimes very long, so leave plenty of time. But there are two security checkpoints - and the one at the far end of the airport (further away from the Easyjet check-ins) is often less busy so it can be worthwhile walking along to it. If you are staying around Place Garibaldi and the Port Area don't forget the small station at Riquier, much quieter than the main station and perfect for the trains going up and down the coast. Also, terminal duty-free shopping is limited and high end so don't leave that last minute gift that you don't want to pay the earth for, well till the last minute!!

6. Wi-Fi widely available in cafes with your coffee and pastry, though internet speed is variable so don't expect to do any movie downloads or streaming while you are away - but basic surfing and email is adequate.

7.  Food prices have levelled out a bit over the past few years with the UK but fresh meat is still expensive as are toiletries and convenience foods. Bottled water is inexpensive in the supermarkets and some consider it a necessity as tap water in France can often be very hard water. In contrast, alcohol can be very cheap - wine and beer from supermarkets, but invariably fiercely expensive in restaurants. If you want wine with a meal, ask for a "pichet" - generic vin de pays, served in a decanter (usualy 50cl), remarkably good quality compared with what was produced for subsidy - "the wine-lake" - decades ago.

8. Finally! If you're a first time traveller to France, it is a good idea to get some French under your belt before you go. This is NOT Magaluf or Benidorm where everyone just expects to speak English. The French are mostly remarkably tolerant of basic  French if you are prepared to have a go, on their terms, and some will hazzard a reply with some basic English if they can, especially younger people. Arm yourself with the information you need before going out, from tourist office, guide books or travel sites,  rather than rely on questions in English to a bus driver or ticket clerk.
