"Will the week days be less crowded than weekends, or with school out does it matter? Any feel for MGM and Epcot crowds this time of year? Lots of pm rain, kinda shoots the pm swim after am parks plan I quess?"
You will actually find that weekends in parks other than MK tend to be somewhat lighter than weekdays, particularly at Epcot and AK. Many have a misconception that weekends are the most crowded because of local resident visits. What actually happens is that Sat and Sun are the two busiest travel days in and out of WDW by out-of-state visitors and those who are traveling on one of those days most often are not hitting a park. Nevertheless MK will be very crowded everyday.
Epcot crowds are generally manageable and most things other than Test Track and Mission Space are easy to get on anytime after 3 even if crowded mid-morning. MGM can have real heavy days and not so heavy days and unfortunately, it is hard to predict which day will be which because we have found, at that time of year, MGM doesn't really follow any rule that its early entry day is the most crowded and others are not. Similar to Epcot, many things can be fairly easy to get on after 4 except RnR, Tower, and Mermaid.
As to the PM swim, it just depends on the particular day. Also note, it is usually more rainy than August and less pattern-like than August. Just over the last 5 years: I have been in June when they had droughts and and saw a brief storm only once every three days; I have been when it is "normal" meaning 3 to 4 fairly brief but heavy storms a day often with the first one in early afternoon; I have been there when a low pressure system decided to just sit over the area for nine days dumping 10 inches of rain and basically just raining for about 18 hours out of every 24 (and that was mostly pouring constantly). It really isn't easily predictable what will happen in June.
