The sentence 'I made just one request for the camping trip: I wanted to stay in a cabin instead of a tent.' correctly uses a colon to introduce an idea directly related to the independent clause preceding it.
The correct sentence using a colon in your examples is: 'I made just one request for the camping trip: I wanted to stay in a cabin instead of a tent.' The colon is used correctly here because it introduces a list of items or an idea that directly relates to the independent clause preceding it. By contrast, in other sentences, the colon is not used correctly as it either disrupts the flow of the sentence or doesn't follow an independent clause. For instance, in 'Anna was happy: to go skiing with her sister' , 'Anna was happy' is an independent clause, but 'to go skiing with her sister' is not an idea directly related, it is just supplementary information.
