I been using my Discover card there for years, deposit, room charges, whole trip. Nothing beats getting the cash back bucks the following month. I put the whole thing on there, thats what our charging privilidges are put on, express check out, no problems and getting 2% back from paying it off is a big bonus. Never could figure other posters using credit, debit all kinds of charges when Discover gives the 2% back.
PS, just saw your other question about the parks: I leave an imprint of my discover card and have charging rights on my room key, room key accepted everywhere, never any problem there. Just returned September, room, annual passes, food and souveniors all on room key. Took 500 bucks cash for incidentials, spent 100 bucks at the grocery and alcohol store and maybe 10 bucks for bar tips, rest I brought home. Complete expenditure was printed out for the trip and hanging on my door with express check out if using a credit card. All we take into the parks or walk around the property with is our room keys, camera and a smile.
