Beaches -Ocho Rios: what do I need to know for our family vacation w. 2.5yo??

[Desperate2012]

Kind of what it says on the tin! I know I need to bring nappies, but should I:

1. request a zed-bed for DS?
2. bring snacks for the inevitable hunger pangs due to jetty at 2am?
3. pack my own UHT milk for last-thing-before-bed?!? (That's crazy? Right?)

Any tips or tricks??

Thanks!
