I love Scotland, so am biased.
As you say, weather could be cak, meaning a holiday here could be a couple of weeks stuck in camper van listening to the steady drum of rain on roof,
BUT, if the weather’s in your favour, you’ll see stunning scemery, gorgeous sunsets (and sunrises if you get up early enough) and long, long days.
So, of your options, Scotland’s either the best or the worst, depending on the weather.
