No — show the mobile ticket on your phone at door 2. Have it ready before you reach the scanner rather than digging through your email in the queue.

Same visit, same 150+ figures — Fast-Track just uses a shorter queue at the entrance. Worth it on weekends and school holidays when the standard line builds up; less necessary on a quiet weekday morning.

You can still get in, but you may join the back of whatever queue is running at that point rather than walking past it — the time on your ticket is when your entry window opens, not a hard cutoff.

Yes, but they still need a ticket reserved in advance so you're not turned away at the door for an unlisted child.

One glass of Pommery Champagne (or a soft drink for under-18s) at the 1835 Bar, on top of Fast-Track queueing — weekends only. Nice if you're already planning a slower visit; not essential if you just want to see the figures.

You book both on one order. Your Madame Tussauds slot is fixed at checkout; the London Eye ticket stays valid for 90 days, so you can do them on different days if that suits your trip better.

Baker Street — about a 2-minute walk. Door 2, on Marylebone Road, is the one you want.
