Spend 7 days at Disney Aulani Resort, first time...

Spend 7 days at Disney Aulani Resort, first time ever in hawaii, to be honest i was expecting a lot more for their room prices and decoration furniture looked old ( scratches all over) housekeeping not a great job, tub was still dirty.
Small rooms, overpriced food everywhere you go, great programs for kids at auntie' s beach house. Luau at Aulani was ok again I seen way better on tv. Hard to decide since nobody tells you about the best one. If you ask employees and people who booked activities they all suggest you Aulani Luau but I was disappointed not to much action, was to slow and boring for my taste, food was good.
My last bad experiance was when I went to the little shop inside the hotel that is called kalepa's store bought like 200 dlrs worth of little gifts and last day of our stay went back to find a few more gifts for people I forgot and found some of the items I purchase a day before way cheaper like some Mickey pens I paid $3.99 and found them for$ 1.99 when i told the girl at the register she even remember us since we bought lots of cups and they took long time to wrapped them. She said hey I do remember you guys!!!.. but since we couldn't find the receipt they couldn't give us the difference. Even though she helped us. She said manager said you can exchange merchandise but we can't give you difference without receipt even do cashier does remember us. Difference was like almost $30 dlrs. I was so upset, expecting better customer service specially after same cashier helped us and told manager she remember us. C'mon Disney very disappointed!!!!!
