I use Sunshine Rewards and CashDuck.
Sunshine Rewards has an excellent forum to help you get started. Both have fantastic customer service and very friendly, quick to respond to questions or concerns. I don't think I've waited more than a few hours for an answer.
If you decide to join more than one, just make sure you don't repeat surveys or offers. What I do is always do offer types abc on SR, and offer types xyz on CD, that way I know I won't overlap by accident.
Again, this is nothing to quit your dayjob over, but great for some extra spending money, etc.
So for for this trip I've put $600 on my room ressie, have $200 disney dollars, and $75 rainforest cafe/trex/yakyeti. This is since I think August when I started cashing out for Disney. You can also get check/paypal, or various other gift cards. Last spring I cashed out for Home Depot and
Walmart and painted the house and new drapes.
I am also a member of buzz agent. They send you products to test and then "buzz" about to people. They pay you in MyPoints so I also have an account there, but that's about all I do with them, and maybe some email clicks. Mostly the buzz agent is because I like to test cool stuff!
You don't need a referral to join (and we are not allowed to ask or give them here on the DIS).
