From newspapers:
"When Neil Dingman recently went on a vacation to Europe, he took his iPhone with him, with no intention of using it much."
"An Edmonton writer discovered that instead of going to Europe, Sather took a vacation in Hawaii."
How is "a vacation to someplace" different from "a vacation in someplace"? Or is one of them wrong?
"When Neil Dingman recently went on a vacation to Europe, he took his iPhone with him, with no intention of using it much."
"An Edmonton writer discovered that instead of going to Europe, Sather took a vacation in Hawaii."
It depends on how you phrase it. Look at the verb "went". (went to Europe)
"He took a vacation to Europe after graduation."
