If you've been trying to find some itinerary ideas for 3 months in Europe I've made a few itinerary's based on a few different factors such as direction, close nearby, interests like museums, beaches, shopping etc.
1. This is my itinerary for 11 weeks in Europe as an example:
Start in London - 6 nights

Brussels - 2 nights

Budapest - 4 nights
Zagreb - 2 nights

Split - 1 night
Croatia Sail - 6 nights

Transfer to Dubrovnik
Dubrovnik - 3 nights
Naples - 1 night
Athens - 2 nights
Mykonos - 3 nights
Ios - 3 nights
Santorini - 3 nights
Rome - 4 nights

Here's the revised version of my own itinerary:
London - 6 nights
Paris - 5 nights
Brussels - 3 nights

If you wanted to change to make it exactly 3 months you could but I think I prefer this itinerary for myself as my boyfriend lives in the UK so that's why my trip starts and ends there, and you can edit to suit your circumstances.
