Planning a wedding plus honeymoon

Will be spending about 20K or more in the next week or so on honeymoon travel with a tahiti trip booked through a travel agent bought via bulk. not eligible to earn points for staying (SPG or Hilton) as buying via bulk. wanted to ask how i should pay for above to maximize the spend.

I was thinking opening a chase sapphire preferred for me and my future wife. that will net 45000 points each assuming $8K in spending. Total of 90000 points here.

that still leaves about $15K - 20K left.

1. Should I just put the remaining balance on the CSPs as well?
2. Are points transferable between CSPs?
3. Should we open up any other cards to recoup bonuses? If so, which?


Did the citi executive AA card x 2 so we are not eligible for that anymore.

Our current cards include:
amex gold
capital one venture
amex blue cash preferred
penfed (5% cashback on gas card)

we eat out quite a bit at restaurants. located in the northeast/nyc area.

any advice welcome


THANKS!
