Hello! That sounds like an exciting trip. I'd be happy to provide some travel tips for your upcoming journey to Tbilisi, Kutaisi, and Mtskheta in Georgia.

Best Time to Visit:
The best time to visit these cities is between May and October when the weather is warm and relatively dry. Specifically, the months of September and October are wonderful for viewing fall colours.

Route and Accessibility:
Tbilisi, being the capital city of Georgia, has the country's main international airport - Tbilisi International Airport. Kutaisi and Mtskheta are easily reachable from Tbilisi by road. A variety of public transportation options, including buses, mini-buses, taxis and trains, are available.

Accommodation and Booking:
Both Tbilisi and Kutaisi offer a range of accommodation options to suit different budgets - from luxury hotels to guest houses and hostels. Use popular hotel booking websites to compare prices and check guest reviews. Mtskheta being a small town, has fewer options but you can find comfortable guest houses for your stay.

Clothing and Essentials:
Pack light summer clothing if you're traveling in the warm months and bring a medium-weight jacket for cooler evenings. Essentials should include comfortable walking shoes, a sun hat, sunscreen, a water bottle, and a good quality camera to capture the stunning beauty of these cities.

Health and Safety:
Georgia is considered a safe destination. However, it's always crucial to have travel insurance, regardless of your destination. While tap water in Georgia is usually safe to drink, it might be a good idea to drink bottled water to avoid any potential stomach upsets.

Local Etiquette and Respect:
Georgians are generally hospitable and friendly. Dress modestly when visiting religious sites, and always ask permission before taking photos in these locations. Learn a few basics of the local language (Georgian) to show respect.
