Planning for Three Weeks in Europe
I am in the very early stages of planning and I definitely have "Do It All!" fever. I'm planning on going for ~3 weeks traveling (thinking of doing a one way ticket and see how the days land once I'm there, but would like to keep it right around 21 days). First time in Europe, not completely new to backpacking light/short trips, very frequent budget traveler.
I've heard people recommend 2-3 days at each city/location to enjoy it. Does that include daytrips? How do you factor that in when planning?
Would you say it's better to spend 2-3 days in every location to see a little of a lot, or would it be better to plan for 5-6 days in each location and only hit ~3 in that time?
I'm looking at the Slovenia-Croatia area. Possible plans to land in Portugal for a few days to hang out with family, hop on a plane/train to jump to Slovenia area. I'm very comfortable on long train trips, and thought this would be a good way to see the Spain+France landscapes without stopping much or at all. I have ideas to jump through Hungary and spend time in Western Ukraine with distant relatives, but feel that may put a burden on enjoying the coast.
I'm tempted on spending the main hunk of time in Slovenia-Croatia area (12+ days), but then I feel like I'm missing out elsewhere.
Definitely just struggling with the mentality of wanting to see it all but wanting to enjoy myself. Big on hiking/scenery/beaches, sightseeing, would love to meet some people and socialize on the way (but I'm not huge on partying), explore local culture as much as possible. Prefer cheaper than not.
