Hello! That's a great choice for your travel plan. Spain is a beautiful country with rich history and diverse culture.

Best Time to Visit:
The best time to visit Spain, specifically Barcelona, Valencia, and Alicante, varies depending on your preference. For great weather and less crowd, consider visiting between March and May or from late September to November. Do note that August is usually hot, and many locals go on vacation, so some places may be closed.

Route and Accessibility:
You can reach Spain via many international airlines into Barcelona. From there, you can take the high-speed train (AVE) or short-haul flights to Valencia and then Alicante. Each city has a robust public transportation system, including metro, trams, and buses.

Accommodation and Booking:
Spain offers a range of accommodations from luxury hotels to budget hostels and vacation rentals. It's advised to book your stay well in advance, especially in high seasons. Online booking platforms like Booking.com, Airbnb, and Expedia offer numerous options.

Clothing and Essentials:
Pack light, breathable clothes for the summer months and warmer clothes for winters. Don't forget a good pair of walking shoes, sunscreen, a hat, and a reusable water bottle. A Spanish-English dictionary or a translation app might also come in handy.

Health and Safety:
Spain is generally safe, but as with any major city, be aware of your surroundings against pickpockets, especially in heavily touristed areas. No special vaccinations are required for Spain. Have your usual medications, travel insurance, and a basic first-aid kit ready.

Local Etiquette and Respect:
Spanish people are friendly and appreciate polite manners. Address strangers using formal titles until invited to be more informal. Traditional Spanish customs include a light kiss on both cheeks in greetings. Tipping is appreciated but not mandatory.
