I recommend visiting the Isle of Man for at least a few days on any jaunt to the UK. Between the hustle and bustle of London and other big cities, you'll love to have a respite in a laid back place with laid back people. In our summer 2017 visit to the IOM, the weather was damn near perfect (after time in the 80+ degree sauna of London): Sunny, an occasional cloud or sprinkle with temps in the mid 60s (Fahrenheit)
And of course, with so much reasonable weather and the long days, we wanted to go outside.
We visited Onchan Park every day of our journey: Mini-golf, bumper boats, tennis, just chillin' on a bench, checking out the north end of Douglas Bay, eating at the nearby cafe ... it's all fun and relaxing. And, we were surprised at the level of hospitality. They don't get a lot of tourists on an island with a complete population around the same as Trenton, NJ, but they were great about letting these yanks access their facilities. A local even let us borrow some tennis rackets and balls, and we tried our hand on their well-kept courts. read more
