I just had a 4 night stay here. I had previous stayed at Grand Hyatt and Park Hyatt. I prefer the location of other 2 properties..
However not a fan Grand Hyatt internet as it blocked my work VPN. This trip I was proactive and purchased a SIM card, which of course ended up not needing it.
The price of the Regency is great, but I prefer the location of the other too.
