We are booked for 7days/6nights at Pop with MYW with park hopping plus dining option. Problem arrises today with my obsessive planning since this a last minute planned trip: SWA offers $39 tickets now if we fly in later on Monday night and leave early Sunday morning. We will lose 2 days at parks. We would save $664 on airline tickets---would we be better off doing that and buying the no expiration on MYW once we got there? This is the first trip for the family of four (DS-8, DS-5). I'm trying to justify losing 2 days at parks with possibly using credit for tickets for trip this fall or early spring next year?! Help me
