The booking process is simple and straight forward from TripAdvisor, simply select the dates you are taking up the tour, the package and then make the payment. The tickets will be available in your TripAdvisor account and you can either print it out or have it ready in your phone. If you are still deciding to take up the castle tickets or not, you can always just get the basic tickets first then make a decision on the actual day to purchase it on the bus, if you outright bought the UPGRADE option then its already provided.
The location to board the bus was easy to find as its just a couple streets down form central Munich station towards Karlsplatz. Simply input the address provided when you purchased the ticket into your google map and you will find your way there. Upon reaching the bus bay look out for the greyline buses, I have provided a photo of the bus and the bus bay area for reference. It also helps closer to the boarding time, a greyline staff would check your tickets and guide you to the correct bus.
The provided itinerary for this tour is very accurate (German precision FTW) thus do cater your whole day for it and please cooperate with the tour guide to meet the timing given. It takes about an hour from Munich to Linderhof and you can either take the time to snooze away or enjoy the countryside view on the way.
Linderhof palace itself isn't that huge like you would imagine it to be, thus the guided tour of the palace lasts about 30 minutes max. Do take note you aren't allowed to photographs of the interior while on tour. The interior features intricate wood carvings, elaborate frescoes, and luxurious furnishings, with alot of marble materials as well which after hearing from the guide it's kind of funny I feel like the palace was built from materials from all over the world except Germany!
Anyway one of the main highlights of Linderhof Castle is the Hall of Mirrors, a stunning room adorned with crystal chandeliers and mirrors that create a dazzling optical illusion.
The tour takes visitors through the various rooms of the castle, including the King's bedroom (which is my personal favourite as its amazing how the view from it is also facing the garden which supposedly would have like a classical orchestra performance back in the days) , the Audience Chamber, and the Dining Room. The tour also includes a visit to the beautiful gardens surrounding the palace, which are filled with fountains, sculptures, and beautifully manicured lawns.
Depending on your tour size and the day of your visit there is a limit to the number of people allowed in the palace at any time on the guided tour, if your tour group is broken in to 3 or more groups you would find some additional time to take photos of the garden outside and also grab a bite at the souvenir shop on your way in walking towards the palace.
After the visit to Linderhof palace you would then take board back your bus to make your way to Oberammergau which is just 30mins away to grab a quick lunch or get some souvenirs if you like. In Oberammergau, I would suggest to take more photos of the richly painted houses and just admire how amazing they are. Since it's a short stop do take note of the time and do not wander too far away from the bus park or attempt a full dining service lunch experience.
Moving on the highlight, the bus ride from Oberammergau to Neuschwanstein Castle takes about 45mins and since it takes the same route back out the way it came in, you may lookout the window and spot more of the interesting houses lining the roads. Arriving at at Neuschwanstein Castle, do take note you will be dropped off at the foot of the castle whereby the tour guide would help get the castle tickets for everyone and distribute them out to you.
The tickets has a time slot for you to visit the castle so do plan your activities at the foot of the castle around it, the estimated time arriving here would be 1:15 PM.
Importantly take note there are 2 ways to go up to the castle, if you intend to walk your way up it would take about 30mins to 40mins at a brisk pace. The second way is to pay 10-12euros per pax for a ride in a horse carriage up to the castle which will take 20mins.
The actual guided tour of Neuschwanstein lasts about 35 mins (the castle was never complete anyway so the tour only takes you to the completed area) and likewise photography within is not allowed as well. When the guided tour ends you are to make your way to the lower levels of the castle which you can continue to explore the castle and from there find a balcony to take photos of the surrounding of the castle which is really stunning.
Finally do remember to factor in your trip back down to the foot of the castle to find your tour bus and make the 2 hours journey back to Munich. You will be dropped off at the exact spot you boarded in the morning.
All in all I find the tour was fantastic and good enough for a day tour if you don't drive or travelling with children in tow. I would recommend this tour if asked in future.
