Fun trips in May and June

So I'm finishing medical school this spring and have most of May and June off for fun. I'm thinking about doing a bunch of smaller trips (ideally 1 week length, 2 weeks at most) and not sure where to go. I'm looking for placesthat aren't ridiculously hot,and not Europe unless there's a gem that won't be too overcrowded.

Live in Western Canada and have been to most of Europe, Canada, California, Texas and Florida.
So far I have a tentative trip to Disneyworld + miami in May.

Anyone have good prior experiences and ideas?

Well if Disneyland and universal studios were in Montana I'd go to Montana. I'm going to Florida b/c that's where the attractions are, not to sight see.

It's purposefully vague but just those 2 requirements (not too hot and 1 week/2 at most length) already limit more than half the planet....

What would the form of the trip be like? Camping/lodges/hotels? Anything unique there? I've done banff + jasper national parks so keep that in mind.

Anyone gone to the French open or wimbledon? good/bad/thoughts? And how much are the tickets exactly? On RG website says finals tickets are "from 270euros". What's the range and where does the 270 seat you??
