According to forum posts, Paris offers a variety of public transportation options, including buses, metros, and trams. The extensive network is managed by RATP, and details on routes and schedules can be accessed on their official website ratp.fr.

Travelers have noted that the metro is the fastest way to navigate the city, with extensive coverage that allows you to be no more than 500 m from a station or bus stop within the city. The RER train is highlighted as a direct and efficient option for longer distances within the city, such as traveling to Disneyland Paris.

Some travelers have recommended specific bus routes for sightseeing. For example, Bus 69 is praised for passing by several major tourist destinations. Moreover, comprehensive bus route maps and schedules can be found on the RATP website, which helps in planning trips to popular destinations like the Louvre and the Eiffel Tower.

Posts mention that a single metro or bus ride costs €1.90, and there are options for passes depending on the length of stay and travel needs. The Navigo Decouverte pass is specifically called out as handy for unlimited weekly travel.

According to forum posts, many travelers prefer staying in central areas such as the 1st, 4th, 5th, and 6th arrondissements due to their proximity to major attractions like the Louvre, Notre Dame, and the Eiffel Tower. The Latin Quarter and Le Marais are particularly favored for their charming neighborhoods and good metro connectivity.

Some travelers suggested specific hotels based on their experiences. Hotel Britannique in the 1st arrondissement is noted for its charm and central location, although rooms are small. Hotel Marais Bastille was highly recommended for its good reviews and proximity to local transport. For those looking for a budget option, Ibis Styles Paris Meteor Avenue d'Italie in the 13th arrondissement was mentioned as a good value with decent metro access.

Travelers have called out that central locations generally come with higher prices. Budget-conscious visitors might need to look in slightly less central areas but can still find good connectivity through public transport. The posts highlighted that budget options are more likely found outside of the very central arrondissements, yet still accessible by metro.

For the best rates and potentially additional perks like free breakfast, some users recommended booking directly through the hotel’s official website. This might offer better deals compared to third-party booking sites.

According to forum posts, travelers have recommended several day trips from Paris. Rouen and Reims are popular choices, with Rouen known for its compact size and interesting architecture, and Reims for its historical sites like the Cathedral and Museum of the Surrender. Both cities are accessible within 45 minutes to 1 hour by train.

Some users mentioned the possibility of visiting châteaux close to Paris, such as Malmaison or Fontainebleau, which are suitable for cold weather visits. For those interested in art and scenery, Chartres is suggested for its magnificent cathedral and stained glass.

For those looking for outdoor activities, Fontainebleau offers opportunities for hiking and biking in its adjacent forest. Provins, another recommended destination, is noted for its medieval architecture and seasonal events, although it's best visited in warmer months as some attractions might close during winter.

According to forum posts, popular restaurant recommendations in Paris include Fish La Boissonnerie for seafood options, Cocottes near the Eiffel Tower for French cuisine, and Chez Janou in the Marais district for its Boeuf Bourguignon.

Some travelers have mentioned enjoying L'Ange 20 for its great food and reasonable prices. Le Grand Véfour, known for its historic significance and impressive setting in the Palais-Royal arcade, offers a memorable dining experience, despite mixed reviews about the food quality.

For a variety of cuisines, Kubri in the 11th arrondissement offers Middle Eastern/African fusion dishes, and Yaya provides Greek fusion cuisine. Both places are highlighted for their vibrant atmospheres and innovative menus.

According to forum posts, the best practice for purchasing tickets to Paris attractions like the Louvre or the Eiffel Tower is to use their official websites. For example, tickets for the Louvre can be bought from louvre.fr, and Eiffel Tower tickets from toureiffel.paris. This ensures authenticity and avoids potential scams from third-party resellers.

Some travelers mentioned that it's crucial to buy tickets in advance, especially for popular attractions, as they can sell out quickly. For instance, Eiffel Tower tickets are available online 60 days before the visit and tend to sell out fast. However, for some museums like the Musée d'Orsay, you might still be able to purchase general admission tickets on-site if online tickets are sold out for your desired date.

For those seeking flexibility, some users have noted that the Parisinfo website offers non-date specific e-tickets for various museums, which might not always allow priority entry but provide the convenience of not being tied to a specific date. Always compare prices and conditions on the official venue websites and check what exactly the ticket entails regarding entry privileges.
