Hey Nick,
Perrochico here, also a fellow Zonie. I'll be there 7-9 April and staying at Sportsmans. I recommend that place highly, but I think they are full during your trip. I have stayed at the Europa Centro ,
www.hoteleuropacr.com, (not the Radisson, but the old one) several times. I have always enjoyed my stays there, but would recommend a room "poolside" as the streetnoise in the morning is a bit much. They should have enough vacancy there (75 rooms in all).
If you need anything while there, ask the bell captain Cesar. He is a nice guy and will take care of you.
Swing by Sportsman and lets have a beer.
Perrochico
