Travel to Hawaii Dilema

Denise is stationed in Hawaii for the next three years and I really want to visit her while she is there. Plus I have been planning my dream Hawaiian vacation for years! The problem is … when do I go? We want to start trying for a second kid sometime this summer. So should I go before or after the second kid? The problem with going now (around May) is money. We just bought a house that needed some improvements and so money is tight. If I go now, I probably can’t have the dream vacation I planned; we would probably just stay with my sister, which would be ok, but then I may never get my dream. My dream vacation involves cruising to all the islands and staying in a nice resort. Also, my sister is a stay at home mom now and so can spend more time with us if we go now but will probably have a job by later this year. If I wait, it will be almost 2 years and then I will have to travel with 2 kids causing the trip to be more expensive and complicated. It would give me more time to save and plan for my dream vacation though. I don’t want to be pregnant when I am there because I had awful morning sickness with my first and I really want to scuba dive when I’m there, which I can’t do if I’m preggers. I could try and plan a trip during the second trimester, but it is hard to know how long it will take me to get pregnant. We didn’t go on a vacation at all last year and I would also really like to get away. It is possible for me to do my dream vacation this year but would involve putting a lot of it on credit cards or borrowing money.
