Global Hotel Alliance Reviews 

Not a very good experience for me. Their website to book hotels is pretty clunky compared to other search engines. They also charge a substantial amount of money for their service (in my case, £57 for a booking worth £400, so more than 25%) that I find difficult to justify and they only tell you about when you’re about to pay. But the worst part was when I received confirmation of the booking with wrong dates. Whether it was my mistake or theirs, they didn’t help at all.
In conclusion: Clunky website, expensive and not very helpful. I’ll never use their service again.

Price is double the amount when using other companies. It's ridiculous

Their definition of an eligible stay is unclear and you don't know at the time of the booking whether it's eligible or not - probably written in some obscure places.
Also, I stayed at Pan Pacific Perth, which is old and tattered. The water coming out of the bathtub is brown...

This is the worst hotel loyalty program around. I have stayed at 5 hotels this year and each time had to follow up to get my stay credited despite providing my membership at booking. I have just stayed at Tivoli in Sao Paulo, and there was no record of my membership so I had to request the 'platinum benefit'. I had also redeemed my platinum 'reward' but arrived to learn the spa had not received it from GHA nor was the spa open at that time despite GHA sending a certificate confirming award with date and time. I wont stay at Parkroyal, QT or Tivoli again. I will stay at Alila as it has seen the light and left GHA and gone to Hyatt. Run for the hills.

Here's a good tip for every one that has dealing with the GHA parkhead in shettion Glasgow can they get away with force in eldly people to live in porcondsion ie damp slug infested places and yet try and pass them self of as GREAT HOME BETTER LIVES !!!! I DON'T THINK SO.these people have been thought the war with these people even had mp stergen just to be told she dose a lot for the refugees this is in Glasgow people wake up

Staff were very very friendly. I strongly suggest Marco Polo Gateway Hotel when you go to Hong Kong. Nice location, beside Ocean Terminal and along Canton Road where designer boutiques like Louis Vuitton, Prada, Chanel, Salvatore, Gucci and almost any famous brands are there. At the corner of the street is the Shanghai Tang where the most expensive brand watches have their own boutiques. And room rates are very affordable, rooms are spacious
