<font color=navy>I took a tour of the Disneyland Hotels in April, and they told us that anyone staying at the Grand Californian can pool hop anywhere, DL Hotel can pool hop to Paradise Pier, and Paradise Pier cannot pool hop. When they had just a plain pool, and especially while it was being renovated, PP hotel guests could use the Neverland Pool, but now that the pool is finished, they won't be able to.
Oh, btw, I stopped by the Paradise Pier Hotel, and took pictures of their pool area. If I have time today, I'll post some pics of the hotel & do a mini review.
