From Getaway Today's ticketing page: Tickets are refundable for a fee, or free with our optional Peace of Mind Plan, if fully unused and refunded within 365 days of purchase. Refunds apply to the entire order, so if one ticket is refunded, all tickets must be changed and repurchased at current prices.
So as everyone has suggested, contact them directly so you can determine if it is worth returning the tickets or if the fee will wipe out all savings.
