It's not the Hawaii you're used to thinking of and seeing ads for tourism.
I always feel that seeing ads for tourism is a little odd here. Should it add a preposition at the end of the sentence, such as "in"? Just as follows:
It's not the Hawaii you're used to thinking of and seeing ads for tourism in.
I guess the latter part of the object "seeing ads for tourism" means that "you can see ads everywhere in the Hawaii". So if there is an of in the former part, why is there also a preposition( in ) in the latter part?
