There are restrictions. Visiting women must wear schmattas. No drugs, no bikinis and no booze. In restaurants, no borsht, matzo ball soup nor chopped liver on bagels.

Visas will be available online for around $70, with no restrictions for unaccompanied women, previously the law. Access to the Muslim holy cities of Mecca and Medina will be restricted. Sadly, you can’t find the Arabian theme any more in Las Vegas. The Aladdin and Algiers Hotels have been closed for years.

It has happened before and will happen again, sometimes involving airline employee strikes, city street riots, stalled cruise ships, hotel fire or other reason. Of course, your immediate task is to get to your destination or home by the most effective way possible.

A: Before you make your next travel plans, check online sources for the latest in Amtrak service between those cities. For example, a recent inquiry about a round-trip ticket by train was $70, while a flight was $240. Of course, there are other costs. Getting from your Long Island home to Penn Station by taxi, bus or local train costs an additional $50, and about the same to JFK airport.

Actually, whatever your choice, it takes a total of about four hours each way from home to destination on either train or flight. And usually costs more than twice as much to fly.
