Yes they do upgrade Platinums but no comp breakfast.
If I remember correctly, you also get 15min (yes fifteen minutes) internet access "per stay" at the biz centre (how generous )

The refurbishment was very well done; the heavy gaudy interiors have been replaced by a modern decor with much slimmer furnitures. Though very modern with plasma tv etc, the decor has a slight balinese touch (sandstone wall with local design). The rooms do feel more spacious but the balcony is still very tight with 2 chairs and a table. The bathroom is also quite small (no separate shower) and apart from a new lighted mirror, the original fittings remain intact.

There is no minibar and coffee/tea is complimentary by "butler" service which is a nice touch. The "butler" will also bring their entire collection of DVDs to your room for your selection .

The local mall "Bali Collection" is a bit more vibrant now with a department store, a supermarket, several cafes and restaurants, and a few boutiques.

The resort does feel very crowded when occupancy is high and appears to be very popular with local Indonesian families. I stayed at the Le Meridien during the same trip, and I much prefer the setting and quieter atmosphere there though the interiors are very dated at the LM.

Overall The Laguna is nice and comfortable.
