Anniversary ideas! HELP

Our 3 years of marriage anniversary is coming up at the end of February. I have no freaking idea what to do for him. I'm a SAHM so I don't have my own money and he pays all the bills and I hate asking him for money because after bills and buying everything for the kids, he has maybe $25 to go to work on each week. He's wanting to get a hotel and spend at least one night there because we don't like leaving our kids for long, but I want to spice things up and make him feel special! What have you done to make it an anniversary he will never forget (sexual or heartfelt)
