What word means both "advantages and disadvantages"?
Solution 1:
Consider mixed experience:
Traveling to England was a mixed experience
I've heard this phrase used to refer to an experience that had its pluses and minuses. Example:
A Mixed Experience. Fern does many things very well. ... In other areas, however, Fern fell short of our expectations.
(A review on TripAdvisor)
Alternatively, how about flip side:
Traveling to England was great overall, but there was a flip side.
Definition:
the negative aspects of an idea, plan, or situation
(Macmillan English Dictionary)
Solution 2:
"Pros and cons" is primarily used for evaluating the utility of a thing or of a manner of doing something. I wouldn't use it to describe something like a life experience.
I don't have a single word for you, but I do have suggestions for re-wording:
I have both positive and negative memories of my trip to England.
I had both positive and negative experiences while in England.
My travels in England had both high and low points.
Solution 3:
How about "My journey to England had its ups and downs." That's a gentle way of saying there were good and bad moments in the journey.
Solution 4:
I've heard the phrase pluses and minuses used in this manner before.
Also advantages and disadvantages is at least occasionally used.
