Are there any lesser-known gyms as an alternative to all the usual chains (ie, California, Seasons, Fitness First, Physical, Hal, etc.). Would like to join somewhere less trendy, where there's less risk of running into posers and people from the office. Are there any hotel-based gyms and how much do they cost?
The hotel based gyms are not all that expensive if you can use them off-peak. Essentially that means any time except 7-9am or 5-8pm. If you can do lunchtimes then they can be relatively good value - the Park Lane has a good package which several of my colleagues used to use when I worked near there.
