I'm delighted to help. Gold will entitle you to 25% extra points added to your base points. At most properties, you will get free breakfast, room upgrades, free WiFi, early check in, late check out, and other perks, but you may have to kindly ask for it. As you stated, do your research on Gold in the Marriott's Reward. Sometimes, hotels will give extra perks just for being nice. I have gotten free parking thrown in, and a snack from the store. I forgot, usually you will always get water included, but sometimes you might need to ask, it just depends on the property and the front desk agent, too. The key is to be friendly and nice. Good luck!
