It is just the annoyance of building work not any discruption. As `Frito´states, the sea front bar right next to Daina (ex Casinet) has been demolished and work is going on there - although this weekend there was a huge hose removing underground water from the site!! This, dependant on work going on during your stay, will cause noise and dust plus an unpleasant view. Directly behind Daina - the huge site of Tango and surrounding buildings (including lovely choc. bakers shop) have gone and this will eventually be turned into apartments as well as another Tangos!!! Further noise and dust from there.
In addition I noticed that the Daina this weekend had their sun terrace around the pool closed as they were re tiling the terrace - and the pool empty!!
However, the road is ok so no problem in getting the cases into the hotel for your elderly parents and dependant on the position of their room they may not be disturbed at all.
