I suspect the answer to your question is Yes. The Ultimate Travel package is a paid-for add on. What would be the point of allowing a user to add this to the Trial version? If that user then decides to NOT purchase the full version of PS he will have an add on package which cannot be used because its "host" program is no longer present.
OTOH, the package CAN be used with Magix Travel Maps as installed with Movie Studio or Video Pro X.
