Ok, I have a dumb question to ask...I was reading this thread about SW boarding etc and would like someone to please explain to me what it is all about? Southwest doesnt have assigned seating I take it? We (me, hubby and son who is 2 1/2) will be going to WDW in Sept and w/SW running the sale right now, for the 3 tix it would be 380 total! So we were planning on getting these today, however after reading this I wanted to make sure that we would be seated together? How does this all work w/them, we have never flown SW before. Thanks!
