We stayed at both the Hyatt Sanur and GH last year (11/04). Without a doubt, we enjoyed the Hyatt Sanur much more than the GH. The hotel was in a middle of an exciting town (Sanur), not in a concrete, touristy enclave. We were able to walk out the hotel grounds, right into the hustle and bustle of the city. The hotel grounds were much cooler as well - the landscaping is amazing! The clubs were similar, both had pretty decent offerings. Best of all, the Hyatt Sanur is even $30-50/night cheaper. That's where I would stay again!
