I am so happy for you. I'm sorry I haven't responded yet to your message. I actually wrote a whole long letter and then the computer I was on shut off (it is not my computer) and everything was lost and I was like crap!!!!!
But as for my opinion...stay in Kailua if you can. It is close by, more beautiful, less traffic, easy to find parking, free parking etc. You don't know how good or ill you will feel afterwards. The less stairs, bumps in the rode, time in the car etc. will be loads better than having to travel to Waikiki. I mean who knows you could wake up and feel absolutely nothing, but just in case. Also if you or your hubby forget something, then your abode is like five minutes away instead of half an hour.
