FAQs about flying to USA
United States climate
The US is a large country and the climate varies by region and time of year. It experiences four seasons, but some areas of the country see a more marked change between seasons than others. The Pacific Northwest has cool summers and mild winters, while just to the south, the West Coast is sunny and pleasant all year long. The Midwest sees a bigger change between seasons, with strong summers and winters and frequent tornadoes and thunderstorms. The East Coast fluctuates and many people head down to Florida to get the warmest winters on that side of the country. Travelling in the off-season can save you a lot of money.

- There’s no need to feel lost in Los Angeles. Purple People Greeters answer questions, provide directions, make referrals or even call the police if things go awry. They’re easy to spot. The Greeters travel in pairs, wear purple teeshirts with “District Safety” or “Downtown Guide”, and can be visited at their Service Center at 801 S Hill St.
- Feed your inner vulture some culture. The San Francisco Conservatory of Music presents hundreds of recitals and concerts by students, faculty and guest artists each year. Most of the performances are free.
- Orlando – there’s not a giant mouse in sight in Harry P. Leu Gardens, 50 acres of lush vegetation in the middle of the city. There is also a restored farmhouse which harks back to a time when space travel was barely imaginable and citrus, not theme parks, was king. The gardens are open every day, from 9am to 5pm. Adults pay $5, school children pay $1, and Monday mornings are free (excluding tour groups).
- Las Vegas – eat well and save money by starting the day with an all-you-can-eat buffet. The Spice Market Buffet at the Planet Hollywood Resort & Casino, a “killer whale in a sea of buffets”.
