There will be building work ~~ the resort is also offering for sale private villas, which are at the back of the hotel towards the beach. If you take a look at
http://www.moborbeachresort.net you will see the plans for the villas. These are going to take some time to complete and, dependent on sales enquiries, I would imagine these won't be completed for a further year or so.
I would like to recommend Sao Domingos, which is a two-minute walk from the River Sal and a lovely seven-minute walk from Mobor Beach. We've stayed there on four occasions and I cannot fault the place at all. Book direct and for £20 per couple per night you get accommodation and wet room, Air Con, anything from the breakfast menu, safety deposit facilities and fridge. All in all an absolute bargain. A separate building with 19 rooms should be available at the start of next season. Also, Edwin owns the Goan Village restaurant, the food and staff are fantastic. Take a look at

Hope this helps.
