1 month itinerary plan for July

[u/Bujair22]

Hi guys, I've been wanting to take a trip around Europe and the 1 month continuous pass is £227 right now (£295 1st class) so I've planned an itinerary and want some feedback on if there are some places I am missing.

The trip will take 25-30 days, depending on if I add more locations or stay longer in some places.

I will start and end in London during the month of July, the plan goes as follows -

1. 3 days in Paris, including day trips to Versailles and potentially Mont St Michel

2. Train to Geneva and then bus to Chamonix for a day

3. Train to Interlaken and at least 2 days there to take in the scenery

4. To Milan for 2 days

5. Half-day trip to Lake Como

6. Pisa for a day as it's a small town

7. Pisa to Bolzano for at least 2 days in the dolomites, potentially longer because I've been wanting to go for so long

8. Through the mountains on a direct train to Munich, including a day trip to Neuschwanstein castle, must see

9. Short hop to Salzburg but I may miss this out and go straight to Vienna?

10. Vienna for a day and a half

11. Bratislava for a day and a half, so Vienna and Bratislava over 3 days

12. Over to Budapest for at least one full day, I've previously been for a day so might need too long there

13. Overnight sleeper train to Prague for the experience and then one day there

14. 2 days in Berlin

15. A day in Cologne, do I need two?

16. Amsterdam for 2 days minimum

17. Brussels for a day, is it worth going to Bruges and Ghent also?

18. Back to London

I will be using the 1st class pass (£295) and mandatory reservations will come up to £200 and then optional bookings around £30, so for £530 am I getting good value?

For accommodation, I've budgeted £1000 as I don't mind staying in hostels the entire time

£300 for tickets to attractions, most things are free to see

£500 for food as I don't mind making my own sandwiches from lidl/supermarkets etc, and one budget/mid-range restaurant meal a day

So all in under £2,500, do you think this a good plan and are there any places I need to stay longer, reconsider or add?
