More excursional can be substituted with a variety of synonyms depending on the context in which it is being used. If the meaning is to imply a sense of adventure or exploration, alternative options include more exploratory, more adventurous, more expeditionary, more wandering, or more adventurous. Alternatively, if the focus is on it being a more extensive experience than usual, more comprehensive, more expansive, more thorough, or more detailed might be more appropriate. It all depends on the specific message being conveyed, but there are plenty of options to choose from to ensure the language used is clear and effective.
