Hey - glad you jumped over! So this is definitely the spot to earn "free money"
It might make sense to peruse the last 250 pages or so (but even that can be daunting, and we're going to use A LOT of acronyms that might go over your head - don't worry we'll help you understand them).
If you have a good credit score and pay your cards off each month this is a pretty easy game to play. Can you answer some questions so we can give some more guided advice:
1) What cards have you applied for in the past 24 months (give us the month and year you applied or approx. if unsure)
2) Do you have any other credit cards that you didn't apply for in the past 24 months?
3) Do you have a spouse or significant other who is also interested in this game? (Maybe is an ok answer here)
4) What are your travel goals - are you looking to cover Disney trips, or do you have more extravagant plans in mind, or a little of both?
Also - if you are on Reddit we have a private group setup there where we log some of the best advice and tips. You're also able to support other DISers there by using their links or share links of your own. If you aren't on reddit it's easy to join at reddit.com. Just send me a PM here on the DIS with your reddit username I'll get you access.
