Thank you. Just got a price through the airline and the multistorey comes in about the same price as the silver zone booking direct. Car is ulez compliant (Suzuki Ignis hybrid).
I'm looking more for convenience and ease rather than saving money as its our first holiday since 2019 for various reasons and its for my wife's 60th, so just want everything to be as smooth and stress free as possible.
The multistorey cuts out potential problems like shuttle buses full etc.
