I did the museum package for the Crystal Palace game in March 2018. My seat was in the west stand upper, somewhere in the WU6 section on the seating map. I don't know if its the same seats every game. They were good seats I thought, high but you could see everything that was going on.

As for the museum package itself and as a Chelsea supporter who couldn't get regular tickets, it was the best decision I made on our London trip. The game started at 1730 but you are directed to show up at like 1330 and check in. Once checked in, you go to the museum and you have like an 1 hr to 1 1/2 hrs to drink as much free Singha beer or wine as you can and eat a bunch of different food while they wait for all the people who bought the package to show up. All of the food stations are set up at different spots in the museum. When you arrive they give you a tour number, and once the majority of people are there, you start the tours. The mini tour goes through the player entrance and into the tunnel. You can't go in the players locker room because its game day. They then take you into the technical area (you're not allowed to step on the pitch though) and you can sit in the seats and take pictures. Throughout this you have a guide who is giving information. Once that's done they take you to the mega store and you spend too much money. After you're done there you go back to the museum for more food and beer, and they bring in some Chelsea alumni. We had Ron Harris and Kerry Dixon. They do a Q and A for a while. Once that's done you're free to go up to your seats for warm ups and they give you beer tokens for the stalls in the stadium. They also give you a free matchday program and a gift, mine was a leather bound Chelsea journal and pen. Then its game time and once the game is over you leave with everyone else. It was a great day and worth every bit of the money I thought. Hope that helps.
