I have used both Aladdin and the Wyndham. Aladdin has been mixed. It was totally overwhelmed the first time we used it and the wait for the shuttle was very long. It's only about a mile away, so when I used them again the next time, I walked to/from the port. I think I used them 3 times in total for parking at the port. They are fine, but make a reservation ahead of time. There will be a sign that says the lot is full, but just enter anyway and you'll eventually find a spot.
I used Wyndham last April. It's right across the street from the ship, so you will need to walk all your stuff across the street. A little longer than directly across the street to get to the crosswalks. I paid for my parking months ahead of time. When I got to the lot, there was only one space open and it wasn't on hold for me. I don't know how they would have handled it if there weren't any spots open considering that I had paid months before. There were several other cars circling the lot, I guess waiting for someone to leave so they could get the parking spot. I think if I use them again, I'll pay for Valet parking, but it's hard for me to trust that there will be a parking place open.
I don't know if Wally Park goes to/from the port. They are great for airport parking. I am going to check with them for my next cruise.
