Bali 7 Days Itinerary

As someone who enjoys both the chaos and a little peace, please tell me if my itineraries works for someone enjoys nightlife, beach and a little quiet. And what do you suggest should a solo girly take if she intends to do more relaxation, less on travelling?

3 days on Seminyak, 2 in Nusa Dua, and finish the holiday in Sanur.

Hotels are booked but cancellable if any changes.

So tell me? Will this itinerary work for me? And oh, no Ubud for me ‘cos where I live, we have what their nature could offer, too, but we lacked in nightlife and the beach.
