The beach club was built for 2008 despite the global downturn.
Given that the first phase of the commercial centre was meant to satisfy the needs of owners and the fact that Calidona itself has a rental business. Wouldn't it have made sense to subsidise the rent on the commercial centre units for the interim? Either they want to develop a succesful business model or not and by not providing such facilities its letting everyone down badly and also would put potential buyers of later phases off.
To make it more attractive to short-term and holiday lets you need to have these things. By attracting more people over it may also mean that the beach club might be utilised more and not simply shut down for the vast majority of the year.
