Im not sure if this has been discussed or not but how does the online purchasing fees work? If you purchase parking, cup, tickets, and FL+, will the fees be higher than if you just purchased the tickets?

The online processing fee varies based on how many tickets are in your order. Admission tickets, Fast Lane wristbands, season passes, and some season pass upgrades all count as "tickets". Currently, the processing fee schedule is:

• 0 tickets (only charitable items, like Coaster Campout): $0
• 0 tickets (only non-ticket items, like drink cups or parking): $0.99
• 1-2 tickets: $5.99
• 3-4 tickets: $7.99
• 5-99 tickets: $9.99

Adding parking or drink cups to your order shouldn't increase your processing fee, since these items are not tickets. Adding Fast Lane Plus might increase your processing fee, as they count as tickets and might push you into a higher tier.
