I'm part of the security preparation committee for the ASEAN. Only accredited photo journalists can get close. In fact, the entire Mandaue Reclamation area and the Mactan Channel will be put on a state of blockade. There will be no-fly zones near the CICC, Shangri-la, Plantation Bay, Hilton, Waterfront Lahug and Marco Polo including the ceremonial routes. That's practically the entire Metro Cebu. No unauthorized boats could get close to Mactan. Shipping traffic would be put into a virtual standstill because every boat will be boarded by the navy and coast guard upon approach to the Channel and departure from the ports.
If you are not security-cleared, - meaning, you don't have one of those IDs that transmit your bio-data when you get close enough to the CICC, you might find the EF 1200mm f5.6 useful if you could find a suitable vantage point.
Anyway, I don't think those Premiers are visually ineteresting
If still interested, good luck shooting those limousines that pass those routes. There is still time to practice panning.
