Go up one block from the first "main" street you come to, for a nicer part of town. And avoid Papas & Beer - holy cow what a scene that place is. And WAY overpriced. Margaritas without any tequila are $8! The shot of tequila is an extra $7 to $9! Damn.
No cruises added

Golf carts sold out fast unless you had a prior reservation. There's a second golf cart rental facility to the right, just past the US Bank building, that had more carts available, though.
Use the "Self Assist" debarkation if you can carry all your own luggage off the ship; you'll be the first group off the last morning. We didn't and had to wait til our group was called to exit the ship. That process takes about 2.5 hours...
