One of the nicest being a grad student is you get to travel, often "for free", to conference held at great places (e.g., Sydney, Paris, Hong Kong, etc.).
Picking such a conference could motivate you to work hard for a paper. :-) So choose your conference wisely. After all. If you have some good work that you can submit to similar conferences that have comparable reputation/prestige, which conference would you send it to? The nicer one of course.
Just remember to check with you advisor that it's OK with him/her though.
