FI just emailed me! We're going to Cabo for a week! We're so excited because FMIL has a job that she has to travel a lot for and has hundreds of thousands of Hilton rewards points and offered to let us use them for our HM. So we're staying at the Hilton in Cabo completely free! We just have to pay for airfare and then food/drinks. My FMIL is the best!!
So glad to have this figured out! I feel like everyone keeps asking me if we've figured out where we're going yet. The HM was FI's one task so I've been bugging him to pick a place. I just wanted a beach and pool to lay out next to and didn't care about doing anything else. This will be perfect!
