Unlike Fester, who i know has at times definitely struggled to get in the pool when he wants to Mrs Medz is in the very fortunate position of being able to go swimming during the day and hasn't, since joining the Llandudno gym a couple of months ago, had any issue swimming when she's finished in the gym.
As part of this deal I personally have booked sessions at Colwyn Bay (I believe it's got a sauna,jacuzzi and steam room but if not I'll just swim) for the end of May and middle of June without any problems. I've even mentioned it to our grown up kids in case they want to get vouchers and come over at the weekend in June as well.
I'll feed back on how it goes but it may be worth getting the vouchers now before they close the offer down.
Not wishing to be impolite but why be so negative? I'm only pointing out an offer I've seen. There's no restriction of having to go to the nearest swimming pool, It's free so I can't see that there is anything to lose by trying.
