Hi all. I'm travelling around the world and only wants to stay in good hotels. - I want the best hotel program, i'm thinking about Hyatt, but how good is it. I have the following questions and I will be happy if you can help me:

1) How often are you giving lounge access?
2) How often are you giving upgrades to club room?
3) How often are you giving upgrades to suites?
4) Is Hyatt Diamond better than SPG Platinum and Hilton Diamond?
5) How good is this program if you are staying on travel agency rates (expedia, priceline) - Still giving lounge/upgrade and/or points?

I'm looking forward to get my questions answered.

I've of course searched a lot on this site, but i'm not 100% sure...
