I use it a lot, the creche has really helped me during maternity leave. You do have to pay £7ph for that but for me it's worth it to be able to exercise. I pay for a year up front as they give a good discount.
Depends on how much you use it and what facilities you use. If you just want a gym, probably not. If you want a pool, spa, racket sports and / or creche then might well be! They sometimes do 2 week trials so you can see if it works for you (or I believe if you join there's a 2 week cooling off period contractually but don't quote me on that!)
What type of membership are you considering? I would say YES as an ex member of a few years, the spa in Emerson’s particularly is incredible! Gym is really nice but same equipment you’d get in any gym really. Outdoor pool is great for summer and they have a little kids park too. What I will say is on my membership (I think it was platinum? It was definitely multi access gyms) you can only cancel once a year which is a huge con for me. I wasn’t getting much out of it once I got pregnant again and was just wasting a lot of money… feel free to message me if you have anymore questions about crèche etc! X
