We stayed at FS for a long weekend last summer, just me and DW. Most of our other trips have been CL stays on property (with kids). I'm sort of a "CL guy" to steal your phrase.
We very much enjoyed our FS stay, but I'm not so sure we'd go back outside of a special occasion. Frankly I'd probably rather go back with our kids than just us, the pool area/facilities are phenomenal and pretty much blow any Deluxe out of the water (even YC/BC). Obviously the whole place is nice, new, clean, beautiful, spotless, etc, etc. Dining options are all first rate. Having true poolside service with quality food/drinks is divine (I wish Disney would up their game on this front). Service is top notch. DW had a spa treatment that she said was one of the best she'd ever had. It was very low key and relaxing, which was perfect (although we did get bored one night and took the bus to Epcot for a change of scene).
But... to us it was a bit sterile and I missed the vibe of staying at a real Disney property (some people probably very much like it for the not in-your-face Disney feel!). I know it's the FS and it just costs more, but I disliked small things like having to pay a fortune for a small bottle of water (vs, say, 'free' CL water readily available). I'd rather have a CL breakfast any day than an overpriced FS breakfast, but maybe that's just me.
I'm glad we tried it - definitely no regrets in doing so. It's just totally a "different" type of Disney experience. On the whole, we'd probably rather stay CL on property if given the choice, even for a couples weekend.
Obviously just our opinion. FS opinions are certainly as subjective as they come! Happy to answer any questions.
