Correct....this is from the "Insure my Trip" site:
The providers will use a few pieces of personal information, other than the cost of your trip, to calculate the cost of a plan:
Age of the travelers
Number of travelers
Length of travel
Type of coverage
The age of the travelers is considered one of the most important of the four factors. Typically, a traveler that is over the age of 65 can expected increased rates. If you are traveling with minors, you may be able to add them to the plan at no additional cost, or at a lower rate – depending on the travel insurance company.
The number of travelers and length of travel can often increase the rates on the plans. This is because with more variables, there is more risk attached to the plan.
...and most policies need to be purchased within 2-4 weeks after the trip is purchased (info from the same very informative website)
