We bought our 2 AP in early May 08. Then DH and I took our twin 4 yr. old gkids in Sept. Now, we are going again with DD, DSIL and twins in January. So we feel like we have made good use of our 2 APs. Now, if I could just figure out a way to convince DH for another trip again in April before we need to renew. But I know, it's not nice to be greedy.
