June: the underrated month
June has all the summer attractions running, with daytime temperatures in the comfortable 22 to 26 °C range. School is still in session in most US states for the first half of the month, so crowds and hotel rates are 20 to 30 percent below July peak. Best time to visit if you can get away before late June.
Top combo for a June visit.
