GOOD ADVICE
Some of the best advice I've ever received (and actually taken) was to "Kidnap My Wife".
1. Tell her nothing about what you're planning.
2. If you're broke, or on a tight budget, just put a little back until you have what you need, no matter how long it takes.
3. Make sure it's not her birthday, or anything else.
4. Make arrangements to farm out the kids.
5. Buy her roses and have them sent to her AT HER PLACE OF WORK on the day of departure. Ten times better than giving them to her at home.
6. Make reservations for a nice hotel (right in town if that's all you can handle). Get a special room, with a large jacuzzi and other special amenities. Take a gift or something special for her and arrange to have it on the table in the room, waiting for her. Premium chocolates are good, gift wrapped. If possible, a diamond under her pillow works miracles. (If you're going out of town/state, tip the porter to take your bags and gifts to the room while you take her for coffee or drink.)
7. Make reservations at a really good restaurant (one that she would like). Take three gifts to the restaurant ahead of time, tip the staff, and arrange to have one gift brought to her with each course, each one wrapped, with a card. Even silly things like a stuffed animal work well, doesn't have to be expensive.
8. Plan for a night of entertainment (a movie, concert, or anything she'd love). Be sure to pack dress clothes for her.
9. Buy her a frilly negligee, something really special (Victoria's Secret works really well).
10. Then . . . . pack your bags (including hers) and pick her up (total surprise) just as she gets off work. Leave her car there (or have arrangements to have it picked up by a friend) and head directly to your destination (or the airport). Make sure that she does no cooking or any "work" for the duration. Even better, take that day off and clean the house, so when you come home she has another surprise.
I did the above, and flew Jenny (first class) to Clearwater Beach at Tampa/St. Pete, Florida for a three day weekend. We slept in, had room service, swam in the ocean and the hotel pool, walked the boardwalks and had a great little getaway. Be sure to bring enough cash to buy her something special for the memory. And don't leave her in the room while you go fishing/golfing - this is her weekend.
I can testify it'll do great things for your marriage.
The wise man who put this idea in my head also told me this . . . . . "The most selfish (for yourself) thing you can do is be unselfish." Man was he right.
I promise you'll never regret it.
