NEED a holiday!

[PunkAssMoFo]

But don't no where to go.

Criteria:
One week (ish)
beginning of March
with a three year old,
Pref warm
Mid budget,
At least a few things to do.

Had a bit of a tough time lately so we do need a bit of chill out time. Would go stir crazy if nothing at all to do. Cultural or nature excursions would be best.
Gimme some ideas including what's good about the place & what there is to do.

TIA.

what do you like to do?

Exploring local area- towns or countryside,
Mixing with locals,
Local sporting events/ festivals,
Seeing something a bit different,
Checking out cuisine.

Nothing extremely out there, just getting out of the hotel to see what's going on.

Caribbean great at that time of year although hot. Lots to do nature wise and sightseeing. Antigua or St Lucia?
