We stayed at the CCI in June, and I thought it was a great value for the money ($113/night with a
AAA discount). Great location, very comfy, nice little breakfast, and helpful staff. To answer the questions:
--We only took the shuttle a couple of times, but didn't have any problems with it. It was there where it was supposed to be when it was supposed to be there.
--The WiFi only worked sporadically in our room. We had to take the laptop out by the pool a few times to get access. But hey, it's free!
--The standard room size isn't tiny, just not really big. CCI's web site says their standard rooms are about 360 square feet and can accommodate a maximum of four guests utilizing existing bedding. It was fine for the three of us, and would work for four -- with DD, the bathroom is always the bottleneck

. They do have deluxe rooms which are 40 square feet bigger and can accommodate a maximum of five guests with the addition of a rollaway bed (extra charge). So with a rollaway, you'd be looking at 400 square feet or so.
