Working the front desk at a hotel can actually give you a lot of relevant experience - not only in working with people, but in problem solving, dealing with difficult situations, dealing with people from different backgrounds, etc.
That being said, in my experience, PC does look at and put a lot of weight on volunteer work, so the one thing I would suggest is looking into some volunteer opportunities now that you can do to beef up that side of your resume. If you do apply and get a denial, I would call up PC recruiting directly and talk to them about it - often times they will work with you; maybe tell you to get 30 hours of such and such type volunteer experience, for example.
When speaking to the recruiter, I would definitely ask about what could make you a more competitive candidate. Some programs require a certain number of hours of volunteer work, and if there is a sector you are interested in, ask about that specifically (I think TEFL might be 30 hours??). I don't know if they maintain any lists of organizations that offer those hours locally, but that might be a question as well. They (in my experience) are really good at suggesting what would make you more competitive, or if you even need to do anything additional at all.
