Next September/October I am going to take just my 5.5 yr old down for a girls trip to do the Halloween party.
We just came back from GF TPV RPC and I am debating on rebooking that or try Contemporary TPV CL. We will just be doing the halloween party and rest of time will be spent in the pool/hotel - opinions? I have not stayed Contemporary since I was little (25 yrs ago) and the theming/atmosphere doesnt appeal to me but I know the views are outstanding
I have done solo
MNSSHP-oriented trips with either DS or DD the last several years...2015-2017 at CR Atrium CL, 2018 at GF (SL, but I've stayed RPC). All 2-4 night trips. Kids in the 4-8 range during those trips.
I find the layouts of some resorts/CLs better than others in terms of being solo with a younger child, but I view both GF RPC and CR pretty similar in this regard. Easy buildings to navigate, no room is very far from the lounge, etc. Both are very convenient.
I particularly enjoy the convenience of CR when it comes to a true MK/MNSSHP trip - just can't beat it... especially when leaving the MK.
I had a bit of probably isolated bad transportation juju leaving MK to get back to GF this year after MNSSHP (just after midnight). Monorail and boat lines were really, really bad. We go enough to see all sorts of crowd levels and transportation lines, but this night was among the worst I've personally experienced. It took just under an hour to get back to GF - way longer than it should take. At that moment I was cursing my decision to do GF and not CR (and I guess from my vivid memory of the circumstances I'm still not over it!).

I suspect this was a bad moment in time situation vs the norm, but stuff happens sometimes.
But, the reason I chose GF in the first place was the pools, and particularly the kids splash pad. This trip was with DD4 so the GF zero entry pools and awesome splash pad gave the edge towards GF given her age and swimming ability. Other than MNSSHP, our plan was to pretty much just enjoy the resort/pool amenities - so from that perspective it was a good choice.
CR pools don't have that wow factor (for me) but I do find the setting beautiful and it's never been particularly crowded in my experience.
From a CL perspective, I am a fan or CR CL and have very much enjoyed our experiences there. I personally prefer CR CL over GF CL overall, but that's probably not going to be the majority opinion on this thread if you took a poll.
Of course, a CR TPV room is mighty nice!
So, I could ultimately make a case for both depending on what's important to your particular trip needs/styles.
Sorry, long winded. Hope it helps and happy to answer any questions.
