Hi pregpan...

Have you chatted to your OB about this? What does he/she think? From memory your not a high risk pregnancy....I went away (to Noosa) when i was about 32 weeks pregnant - i must admit i did pack my hossi bag JIC ! the only negative i can see about going at 31 weeks is it might be slightly uncomfortable for you at times - on the plane etc. But if you, DH and your OB thinks its a plan.....i would go for it, you never know when the two of you will be able to do it again - alone...

Good luck.
