"Tourist" is one of the fallers (7)
I believe the answer is:
tripper
'tourist' is the definition.
(I know that tripper is a type of tourist)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tripper that I've seen before include "at risk of sustaining injury?" , "who might get a booking?" , "person having highly enjoyable experience?" , "Person on an excursion" , "Person on pleasure day out - sounds unstable" .)
