Do you enjoy sweating it out in July among the masses? Then ignore this thread.
Beaches during the summer? That's where everybody goes. Head for the mountains instead.
Hire a VIP greeter at the airport, starting at $75. Whisk through customs and smile knowingly at those waiting in line.
Book a private tour in advance, as the tour guide has private arrangements for off-hours visits.
Consider private airport suites so you don't have to mingle with the sweaty, stinky commoners. More importantly, separate security and check-in! The other option is lounging on chairs with questionable sanitation.
Advance hotel check-ins. Just pick up your room key and skip the line.
Disney World, etc., arrive when the gates open while most people are still breakfasting.
Less travelled destinations. I provided plenty of those in another thread. (Again, sorry about Minsk.)
Postpone your vacation until the kids are back in school. Avoid bank holidays. Early September comes to mind. My neighbors are taking their kids to Disney World on a weekday in September. The kids are straight-A students so no worries. #smart
For some of these tips I'll channel Johnny Carson. The old folks will understand: "I did not know that!"
