Can someone help me plan my trip to vegas?

I am taking my wife to vegas for her 21st. We are arriving july 4th and staying 4 nights. I booked a room at the Paris, but want to make sure this is a good choice or should I cancel and book somewhere else. We are flying from georgia and this will be our first trip to vegas and our first time flying. We dont need anything extravagent like wynn or venetian b/c we dont plan on spending that much time in the room, but dont want to stay at a dump either. As far as shows go, Im not sure what to do, we have never seen a cirque show, but have been to le grande cirque in myrtle beach, which seems to be very similar to mystere? So should we just check out some of the other shows or is going to a show even necessary? I dont want to have reservations during the whole trip and feel like we are on a schedule, but I dont want to miss out on everything. As far as eating goes, we will probably do buffets, food courts, and deli's and maybe go to mon ami gabi and emerill's new orleans fish house (Im from new orleans). Hotel and air will be payed for and Im planning on bringing around $1500 to $2000. Does this sound good
