Heading to Curry Village next Wednesday for an overnight with some relatives who have never been to Yosemite. I've never really been in the Valley during the summer high season, except once one August for a half-day and the traffic was horrendous.
Will there be a ton of traffic getting into the park and to the Valley?
At the entrance gates, from 8:30 AM to about 3:00 PM, Yes, there will be usually a long line of cars. Sometimes (but not always) they'll have a separate line open for park pass holders and employees. That can speed up the lines through the entrance stations. Within Yosemite Valley itself during summer
WEEKDAYS if you get there before 11:00 AM, traffic won't be so bad and you should be able to find parking at Curry Village or somewhere else. After 11:00 AM, finding a parking spot will get exceedingly difficult until about 4:00 PM when it starts to ease up.

Crazy crowds?
On Summer weekdays during low water years, not really. Yes, there will be crowds, but when I was there last year in mid-June mid-week, the crowds were actually quite low. Felt more like late September crowds than mid-June crowds. This year due the late rains, there was more water going over the falls, so the crowds were larger. Still mid-week summer crowds during low-water years are manageable inside Yosemite Valley. Just get there early and find a parking spot.
And if you're planning to leave Yosemite Valley to visit the hight country (Glacier Point, Tioga Road/Tuolumne Meadows) or a giant sequoia grove, get to (or beyond) the Yosemite Lodge before 1:00 PM to avoid the worse of the daily traffic jam that occurs on Northside Drive between Curry Village and the Yosemite Lodge.

Loud adjacent tents?
At Curry Village? Unfortunately, that's always a risk. If they're too loud for too long, just inform the front desk. They'll usually send someone out to quiet the noisemakers.

Mosquitoes? Trying to set expectations.
Mosquitos will be active in Yosemite Valley when you visit (though they won't be as bad as they are now around Tuolumne Meadows). So definitely bring some insect repellent with you (also insect repellent clothing if you have some). Depending on the weather conditions (breezy vs calm air), the mosquitos might just be minor nuisance in the Valley right now, but some years they can be a major pain even in late June.
