I just got back from London and after spending so many hours on this site finding so much helpful advice, I thought I'd repay and write a review about the three different companies. I went on the Canterbury,Leeds,Dover,&River Cruise tour by Golden Tours. I went on the Stonehenge private access, Bath and Lacock tour by Premium Tours. I went on the Brighton,Arundel,& Ashdown tour by Evan Evans Tours. So here is what I had read and was mostly concerned about: I had read many bad reviews about Premium and was worried about being left behind on the tour. I had read Evan Evans was the best (although they cost more). I had also read that Golden was just "okay." Here is what I think: FIRST OF ALL, CALL THE NIGHT BEFORE ON EACH TOUR YOU GO ON TO RECONFIRM AND MAKE SURE THEY REMEMBER TO PICK YOU UP - I forgot to, and thus had a few minor problems. About GOLDEN TOURS: Golden tours was my favorite and the guide was the best of all three tours (although guides in all tours can be very good). Leeds Castle was just ok - probably cause it was lived in up until about 20 years ago, so the interior is modernized and not so "ancient" feeling. There are some bird aviaries in the Leeds castle that are cool. I really liked the bush maze and actually got lost - but there is a worker up in the middle of the maze that watches people and helps them get through. Canterbury was neat, but lunch was just okay - there are so many cute shops and such that I would not do lunch and use that time to shop around! Thames river cruise was neat - they were tickets on a catamaran and it was a nice end to the day. It dropped us off literally across the river bank from the London Eye and a little down from Westminster - so great location to end up at! I was supposed to be picked up from the Millennium Knightsbridge and the concierge was very helpful. I waited until around 8:40 (pickup time was 8:15) and when the concierge called the Golden office, they said the pick-ups were running really late and to just catch a cab - which they later reimbursed me for. For all of the tours I went on, I was about the last hotel to be picked up from and so when this is the case, all of the tours were running at least 10 minutes late. Once I realized this, I relaxed a little and didn’t feel like I would be left so much. About PREMIUM TOURS: Our guide was pretty eccentric, but I never felt like the bus would leave without me. There is not enough time in Bath, so hurry through the Roman baths and see a little of the town. I did the "Jane Austen Museum" and felt like it was kind of a rip-off. It is about 10 USD to sit is a room and hear a little more about Jane Austen for 20 minutes and then to walk around like 3 rooms where there are dresses from the movies. The dresses were cool and the 20 minute talk actually had some things in it that I did not know. So I guess it is worth it , because when else are you going to be in Bath in your life. Just know it is not amazing. The Roman baths were cool and I am so glad I went there! The Premium tour was a private access Stonehenge with Bath and Lacock. The George pub in Lacock was INCREDIBLE and truly the BEST food I had while in London. There is nothing else to do in Lacock, so definitely book the meal option! I had the chicken item and it was incredible! The private access Stonehenge was SOOOO worth it – you get to walk in the stones, sit on them, kiss them, or whatever you want – pretty neat! The only negative thing (if you are like me and love gift shops) is that the gift shops were closed (since it was after hours). But truly, don’t do Stonehenge any other way! I guess if there is a tour group that also includes Avebury (another stone circle) that could be pretty neat to see. ALSO, BRING A METAL COAT HANGER WITH YOU – I forgot and wished I had. The site is a magnetic field, so you are supposed to be able to bend the coat hanger into an L shape, hold it out in front of you, and it will turn on its own. About EVAN EVANS TOURS: This tour company is definitely the most pulled together. You get picked up and taken to their bus depot. Everything is numbered and labeled so you know just where to go. The office was helpful. I did a select tour to Arundel, Brighton, and Ashdown forest. I LOVED IT!!!! ARUNDEL CASTLE WAS MY MOST FAVORITE THING ON MY UK TRIP! Brighton was pretty neat – I did the castle in Brighton and kind of ran through it (which was ok with me because it was unique but not earth-shattering cool). VERY WINDY in Brighton, so don’t wear a skirt like I did! My guide was nice and this tour only had 7 people on it – nice to be in a small group :) So this is my review - I hope this helps people decide and have a great time visiting outside of London!!!
