Our next vacation- help

We are trying to figure out our next vacation-

Can you ladies help us pick a destination?

Here is some info:
1-we love to sit on the beach and relax-
2-Aruba is our favorite island
3-We are not crazy about cruises
4- DH suggested Lake Tahoe- ?
5- Have done Vegas, Disney, Canada and numerous caribeean islands
6- This will be our last BIG vacation before kids-- and Godwilling I will be pregnant on this trip

Time is flexible but I was thinking April/May

Any suggestions?

If $$ is not TOO much of an issue, how about Hawaii?? It is so romantic and beautiful, plenty of gorgeous beaches, and probably not a vacation you'll be able to take once you have children.
I think it would be an amazing 'last' trip as a couple!!
