It is not clear what you are asking because it isn't clear what you mean by 'standard'. Standard what? If you mean 'Which one is in standard English?', the answer is that they both are. Both are written in correct, standard English. If you want to ask what the difference is between the two sentences, the answer is that the second gives more information. In the second, we know that it is that the writer is considering going on package tours (probably along with their family) and that this will save them money. The only thing which is a little odd about this sentence is the phrase 'taking part in..'. This doesn't collocate well - we'd normally say 'going on packing tours' or 'taking package tours'. The first sentence may have the same meaning, but it doesn't make it clear that the people saving money are the same people who'll be going on tours. In the first sentence, it could, for example, be a company sending its employees on tours. Providing the context is clear, the first sentence is probably preferable.

the 1st one is standard
