We're considering going to that there London for a week later in the year and I'm trying to work out how much it'll cost. Two adults, two kids (8&10). Plan is to go to Harry Potter studio and Legoland so we're looking for somewhere reasonably easy for transport to from an airport (don't mind which, can get flight to/from Heathrow, Gatwick or city) and main attraction. I've never been to London so I'm totally clueless about where to start looking. Any suggestions for areas or even specific places to stay would be an amazing help.
