Hello!
We go to DL about every other month, and have stayed at virtually every place on Harbor. You must remember, they are ALL 1950-1960's style MOTELS. They are all relatively clean, yet definitely dated in decor and some furnishings/carpet.
We will not return to the Del Sol. We found it dark and the rooms we had (2) were very large, but fairly depressing. Mid-afternoon we had to turn lights on due to a lack of natural light. We had ants in both rooms, and had no good response from management.
Personally, I can take most anything for a quick weekender. However, you have time to research some other places. IMHO, I suggest you do that.
