If it doesn't bother you to travel alone...go! You don't need to miss the trip because your DH can't come. You can turn it into a very special mom & kid trip!
In the past year and a half, I have gone on 4 different Disney trips alone with my children.
*Feb of last year, I drove to DL with 3 of my 4 kids. My DH and oldest DS flew in a few days later. We had a great time! I think it is easier sometimes to do things without my DH along... because only my opinion matters!
*In March, I took, my oldest DS (15) to WDW for ESPN the weekend. He planned out our whole schedule for the weekend, including the restaurants for our ADRs.
*In April, I took my youngest to WDW for a spring break. She also planned out the whole week! She even picked what DVC resort to stay at.
*In May, we did the
DCL transatlantic cruise. My DH couldn't get out of a business meeting in China, so he meet us at our first stop, Portugal.
I think there is something special about being able to spend that one on one time with my kids. It is a time that is ALL about them. Where I don't have to be the 'nagging' mom. I can be the fun mom, that rides the rides and lets them have junk food for snack.
Go, you will have a great time!
