Hello, we are going to London in March, myself, husband, and 2 kids (ages 13 and 10). We want to do a daytrip to Bath and Stonehenge. I've been a few times myself but it will be the first time for everyone else. I know we can do a tour on a bus, but my husband hates tours and we like to go at our own pace. I was looking at doing the train, train from London to Salisbury, it looks like we can get a tour bus from Salisbury rail station to Stonehenge, and then train from Salisbury to Bath, and return on the train Bath to London. It seems like prices could add up quickly doing it piecemeal like this and I'm not sure about the timing of the trains.
Another option would be a car rental. My husband wouldn't be opposed to renting a car for the day and driving but I'm not sure where it would be best to pick up the car rental since we would be staying in central London.
Any suggestions if there is a better option that I'm not thinking of? Thanks!
