Here's a link to the county of Midlothian. After the 1974 boundary changes. Musselburgh is definitely in Mid Lothian.

Musselburgh isn't in Edinburgh, it's not even in the same county.
It's £3 now for a day ticket on Lothian buses. http://tinyurl.com/3xmjwru
There are many guest houses on Minto street, which is a main road into the city from the south. All the buses use that route and, it's only five minutes to the centre on the bus.
AS they say there is more life in a glasgow funeral than an Edinburgh wedding so perhaps your going to the wrong city
