If your prof will let you attend another section, that would be the ideal solution. I completely understand not wanting to miss any parties because you've got lots of 'em to attend.
For the most part, no one's telling you what to do or not to do - just to be sure that you won't get kicked out of rush if you do skip class. Some schools will release you automatically. Check with the Greek life office and see if this is the case, and if so, make SURE that if you do get the option to attend another section that your professor writes you a note so you can let Panhel know.
This is one of the myriad reasons why night classes blow chunks.
