DAY 1 - Arrive by Heathrow Express to Paddington Station. Find the Paddington Bench and statue and get your photos before heading into the new and very expanded Paddington Gift Shop. You'll want to stay nearby. Baxter's favourite hotels are the Best Western Mornington Hotel or the Royal Lancaster. Both are close to the Lancaster Gate Tube station for easy access around London.
DAY 2 - Since you are staying right near Hyde Park go and visit the Serpentine Lake where Mrs. Brown hangs out in Paddington 2. If you want to explore the entire park and Kensington Palace allow a full day.
DAY 3 - Time to head over to the Shard as it features prominently in Paddington 2 but wait... it's best down just before the sun goes down so you can see London in the day, at sunset and after dark. So since it's pretty close by do the H.M.S. Belfast first. It's a big old ship and will take you at least 3 hours.
DAY 4 - That's right...it's a look back at the original Paddington movie with a trip to the Natural History Museum. Allow at least 1/2 a day.
DAY 5 - That's right...it's off to Tower Bridge because of course Paddington crosses that landmark as well. First stop is the Tower of London for at least 4 hours but ensure you walk the bridge and do the Tower Bridge Experience. It's really good fun.
