The dining plan is not worth it at DL, you pretty much break even with cash. It's not like the one at WDW at all! Also February is great if you avoid the very middle. I have found that the first week and the last week are awesome. We have gone in February two years in a row, this year will be our third. Both times we had walk ons for most of the trip!
We will be there the 6-10, when are you going?
