Stayed here for 4 nights at the end of October. Our 3rd stay here this year. The new road to Nusa Dua makes it a breeze to get here from the airport but the new airport terminal remains slow at peak times.
Booked a Studio room (around USD190++) and used upgrade vouchers. The Laguna has not given us a free suite upgrade before or indeed a room upgrade from regular room to studio. We find the studio rooms a lot better than the regular rooms and can sometimes be cheaper. In the event our upgrade vouchers got us the suite.
We always ask for the top floor (4th floor) as the lower floors can be noisy and are more prone to damp issue.
Plat benefits remain free breakfast instead of the 500 points. You also get a one-time 20% discount at the spa...which meant my wife went once to a very quiet spa. She reckons it's a good spa, though. I think SPG members get 20% off food (possibly drinks as well, can't remember). Lifetime Gold members get a free one-hour massage on their first visit.
They've got a good gym with new equipment and friendly staff running it. Unlike a recent poster we had a very good meal (steak) at their seaside restaurant. Breakfasts in the main restaurant are also pretty good. The Melia hotel just down the sea walk (to the right) has a nice restaurant overlooking the beach with mediocre food but lovely setting. Buy one, get one free beers up to 7pm :-). The Bali Collection gathering of shops, spas and restaurants is quite a bit cheaper and the food quality seems to improve each year. Easy walk from the hotel.
Overall, the hotel continues to provide very good value IMHO.
