Turkish is the official language throughout Turkey and it's the common language throughout the country. Still, in Turkey and Antalya there are sectors of the population who also speak dialects of Arabic. But there are more and more people, specially those working in the tourism sector, who also speak English and German.
Antalya has the typical Mediterranean weather with loads of sunny days and mild winters. It is on the Mediterranean shores so the temperatures are fairly warm throughout the year. Summers -from June to September- are dry and hot with a temperature of about 25°C (77ºF) on average. Winters -from December to February- have an average temperature of 11ºC (51.8ºC) and it's the rainiest season along with fall that is from October to November.
The official currency is the Turkish Lira, though the euro and even the pound are also used as currency. It's best to have Turkish liras with you, specially to pay for the first travel expenses and once you settle down, find out if you can pay in euros or pounds. In Antalya, you can exchange money at the airport and in several exchange offices across the city, especially downtown. Some places will ask to see your passport in order to do the exchange. Another good tip is to count the money to avoid any mistakes. And do not forget to keep the receipts so that when you leave the country you can exchange the Turkish liras back into your own currency!
Although tipping is not mandatory, it's the norm, especially in restaurants. Many Turks are accustomed to tourists -especially Americans- to leave 10% or 15% tips.
2-3 nights. Is the minimum you'll need to get to know this coastal city if it's the first time you go there. We also recommend that you spend some more time visiting the surrounding areas or to get on a plane and visit Turkey's capital, Istanbul. You can also head to Cappadocia among many other places in Turkey.
Antalya stores generally open Monday to Saturday from 9a.m. to about 8:00pm though there are also places that close before this. Malls open longer hours, from 10:00 am in the morning to about 10:00pm. Sunday is usually a day for rest but you can find some businesses are open. Banks work from 9a.m. to 5:00pm though it's better to ask for the business hours once you're there. Schedules are slightly altered during Ramadan, between September and October.
