He told me that we will look at the prices for each of the places, and that we will go to one that we could afford.

Update: I get what he means now. He means that although he too wishes we could travel somewhere far and expensive, he still wants to keep mindful of his financial sense while doing so, and that we could get the same/similar experience elsewhere.

Update 2: Those are two examples of similar experiences for less money.
