Hello all!

I'll be flying to London, Rome, Paris, Edinburg and Bombay in December-January and between those places, my girlfriend and I plan to visit a LOT of museums, aquariums, theatres, amusement parks, concerts etc.

I'm planning to buy most of these tickets in advance.

What credit card would be the best for either points or cashback?

I have Chase Freedom,Sapphire Preferred,Explorer,British Airways,Priority Club and Marriott Premier.
I also have BOA visa signature, Discover, Amex Business Platinum, and a paypal credit card that gets me 2x (or 3x) points on paypal purchases.

Thanks for reading!
I'd appreciate any help, ideas or suggestions...

PM me if you have any tricks that you don't want to disclose in the open... I have a few of my own that I plan to use, let's compare notes.
