I say go for it!! You have the opportunity to go somewhere you have wanted to go, hubby will be there, you will get to do what you love - let's face it the reasons to go are way more substantial than the reasons to stay home. Get an audiobook or two for the drive and GO GO GO!
PS Here is a good rule for staying out of trouble: If you can't afford it and/or don't need it for something you are working on right now, don't buy it. It has kept the dollars in my wallet on more than one occasion.
Have fun!!!! :-D
