The Big Island was our #2 choice, I expect it will be a lovely vacation for you! The travel case we found on Craigslist for $40, a steal with a retail value of $300-400. Combine that with a $75 baggage fee and it is less expensive to travel with our bikes than rent them. Plus, we know/like our bikes & what they are capable of- they are lightweight. The rental shops on Kauai all had Kona's which are pretty heavy compared to the Specialized bikes that we own. My boyfriend is 6'3" and has a 29 inch bike, hard to find in a rental. I am very excited about this trip, it will be the first time to Hawaii for both of us and we are so thrilled that we can bike instead of having to rent a car- that's a cost savings in itself- traveling on a budget! Our next obstacle is food- I've heard that Hawaii is quite expensive, so we are trying to stock up on healthy snacks (love dehydrated mangos!)and figure out a way to cook fresh seafood and veggies. Perhaps packing a Jetboil system & a hotplate? Any ideas?
