Flights booked, what next?

With some good reward availability, a decent sale and one ex-EU my travel plans for 2016 are complete. I normally book a month before so this is very different for me but every time I've looked at prices or availability recently it's been too good to pass. All VS Upper
which I'm very pleased about and 3 VX First flights which I'm really excited to try out. Was hoping to make Japan in 2016 but that can go on hold for another year.
Jan - BOS & NYC. £950. MPM.
Mar - DXB. £880. (M/K - both uprgaded with miles [FlyingCo])
July - Into SFO and out of LAS. Dublin the night before. £930.*
Sept - MCO. £1700. It's my 30th so this was slightly above budget but hey, screw it.
* - I've had trouble recently finding these flights on Expedia. I was using the multicity option which wasn't working. Managed to get that fare tonight and very happy!
Couple of questions...
1. Any hotel suggestions for SFO, SEA (can't wait for the Boeing factory again) & LAS?
2. Any quick legal schemes to pay for all of the above?
