We are a family of 5, arriving Heathrow on a Thursday afternoon, leaving St. Pancras on Monday at noon.
My kids are 17, 15, and 12.
Hotel is St. Ermins, which is near the St. James Park stop.
I am trying to determine if taking the tube to and from the hotel is going to be difficult with our luggage (each person will have one medium size rolling suitcase plus a small backpack), and whether we should plan on a car service from the airport and taxi to St. Pancras instead.
During our days in London, I expect we will take public transportation a lot as we visit the typical things tourists do.
Also, since we will probably not travel all that much on Monday (heading straight St. Pancras after checking out of the hotel), I'm thinking a 7 day Travelcard might not be worth it, so then I thought we would just do pay as you go Oyster. However, the kids pay full fare with those, so then I think we should do something else? Oh, this is so complicated!
