Any time up until September is good.
The way that these places work is that you will start with all the pubs and bars at one end of the strip and by the end of then ight end up in the clubs at the other end, I went two years ago and pretty much every bar/club was great apart from the ones sprawled in union jacks.
Danelis apartments is about 5 minutes from the strip and where we stayed, it also has an excellent swimming pool and serve food all day long, also the owners will keep the bar open all night if you want to start drinking there.
Cooking will not be an issue as there are literally hundreds of cheap places to eat out, including the hotel food itself.
