The free Excursion subscription allows you to plan a single short trip of a few stages.
You will be limited in the amount of information that can be added to the trip plan.
However, the Excursion plan gives you access to all the features.
In fact, this free plan is designed to allow you to take a tour of the application, to try it out, before deciding whether you want to use it to plan your trips.
As an Excursion user, you can add another user's trip and be able to view its contents. But you can only have one trip in your account at a time. So you must delete a trip before you can add another, whether it was created by you or someone else.
Once you exceed the limits of the free subscription, you will be able to sign up for the Escape account to unlock the limits and continue planning your trip.
The Evasion subscription currently costs $60+tx per year.
The price of your membership will always remain the same as long as you maintain your membership year after year.
If after one year, for example, you don't want to renew your subscription, your account will revert to Excursion.
At that point, you will have free access to everything you added during the time you had your paid subscription. You will have access to all your information but you will not be able to modify or add to it.
