Wiltshire area visitor attractions

HI, I'm popping down to Marlborough for a couple of nights tomorrow then up to the lakes for a couple of days with my fiancee and another couple,

She's desperate to go to longleat safari park, also thought about doing the cheddar caves and Stonehenge, are these worth it or is there somewhere else that is a must see since we're that far south

Reckoned a day for longleat then cheddar and stonehenge the next day, or possibly stonehenge in the evening after longleat???

Any opinions options welcome.

Also good, inexpensive restaurant in marlborough??

If you're going to Cheddar then go to Wookey Hole as well, its not far and IMHO Wookey hole is better.

Theres nothing to do at Stonehenge just park up have a look at it then you're done. Theres no shops or anything so it wont take you much time to have a look at Stonehenge itself.
