Honeymoon Trip to Switzerland and Italy

Hi all,

Planning my honeymoon to Switzerland and Italy. Hoping to have some advise for better planning.

Day 1 - Leaving from SG to Zurich (KLM flight). Arrive afternoon.

Day 1, 2 - Staying 2 nights in Zurich
- 1 day free and easy in zurich
- 1 day tour to Einsieldeln to view Benedictine Monastery and back to Zurich

Day 3 - Take SBB from Zurich to Lucerne and stay for 1 night.
- 1 day free and easy in Lucerne
- 1 day visit to mount titlis and left Lucerne to St. Mortis

Day 4 - Night stay in St. Mortis (Planning to come here just to take the glacier express train to Zermatt)

Day 5 - Overnight one day in Zermatt and transport to Venice

Day 6 - Staying in Venice for 3 days

Day 9 - Leave Venice to Tuscany (PISA - day tour) and go to ROME.

Day 11 - Back to Singapore from Rome (KLM flight)

Just wondering, I can get Eurail pass to cover my transport in Italy however can i use Eurail Pass to cover buses like swiss pass?

Btw, any comment on using Airbnb? Wondering will it be better than getting hotel stay.
