We stayed at Paradisus Princesa Del Mar Resort and Spa, adult only but a good cross section from late 20's to "I think he's a stroke survivor".
This resort has a collection of 3 story buildings so you don't feel as though you are lodged in an apartment. Large grounds if you want to do a lot of walking jogging without leaving the property. Double deck buses feature a one price and hop-on hop-off all day.
If you want top notch meals I wouldn't go there, the food was good at most places, I'd recommend the small grilling restaurant down by the beach. You can book into theme restaurants up to 4 times a week. We choose The Hilltop (beautiful ambiance, violiin and acoustic guitar to help digest the food). Also went out for Chinese, Italian and Japanese which was the best. At the Japanese restaurant the food was prepared/cooked at the table right infront of you, very entertaining!
The buffet was quite good, very large so you didn't have to wait to get seated.
From the resort you have many options to get to Havana. We took the day tour, leave around 8am, get back around 7pm. Our guide was fantastic, entertaining and knowledgeable.
Then there is a tour which also includes a nightclub show at the Tropicana, gets back at 2am, or you can go for the gusto and stay overnight in Havana.
My wife is more of a foodie than I am (I'm not at all) so she was a bit more critical of the food, however we both recognized that they are doing the best with somewhat limited resources. Once again I have to say the Cuban people are fantastic!
I'd much rather go there than to the RIU on Paradise Island Bahamas, all they had was a beach/pool and an apartment style building. The Paradisus is a much larger complex, much more variety. Far less aggressive "salespeople" on the beach.
On the bus from the airport it was a 50/50 mix of families and couples, Cuba felt very safe, was a lot of fun.
I believe it's been years since Americans were fined for visiting Cuba, they don't stamp your passport so it would never show up. It would make sense to bring CDN $ to convert to Cuban pesos (CUC) so you don't get hit with the surcharge on US funds. I think about 80% of the people visiting are from Canada so even the tourists are very polite 
If anyone needs any more info PM me your phone number and I'll give you a call.
Damn you guys after writing this I feel like jumping back on a plane.
I'll post a few more pics later today, at 7am I'm off to make my Nissan service department richer.
