First they have announced the opening times which you can find here. That is, 5:30am to 10pm on weekdays with week end opening as well.
Then there is a special offer, available untill 12th February only, of full monthly membership (unlimited fitness classes, gym and swimming) for £29 per month (normal charge £44.50).
See here for the Edinburgh Leisure site for the Commie Pool.
* Now that opening date for the Pool. That is still a closely guarded secret. It should be well before the summer which was predicted when I recorded the closure for refurbishment on 1st June, 2009. It shouldn't be long now.
