CP Heathrow is a nice property too, and they usually put Plats on the club floor with club access.

I have once before walked from Marlow station to the CP Marlow. Its probably about a mile and is fine as long as you know where you're going.

For those not in the know, Marlow is the last station at the end of a branch line with a standard service of 1 train an hour. For most of the day you need to change at Maidenhead for the Marlow shuttle, however at peak times you sometimes also need to change at Bourne End for the finally shuttle to Marlow. It's fine if you're travelling light but maybe not so good with luggage.

Also note that Marlow station - being at the end of a branch - does not have great facilities. It is little more than a raised concrete walk-way and I'm not even sure there was a taxi rank there!
