You are right. I should know better than to use such an ambiguous term as "inexpensive".
We arrive the first night at 9:30pm, so I wouldn't want to spend more than $100 for a room in which to crash for the night. This will probably be the most difficult to find, since I don't want to stay in a run down motel. I just booked the next night, coincidentally, with HHonors points at the Hilton. But at $600 per night, I didn't want to add another night there and I only had the points for one night. However, the last night is open and I would be looking in the $150-200 range for that. Usually when we travel I can easily spend the high numbers (e.g. Four Seasons, etc.), but I struck a deal with my s/o (at his insistence) that we would only go on this cruise if I didn't spend a lot of money on the extras. We are even using miles for the plane tickets (AA in F/J). Staying on a budget is not something to which I am accustomed, but a deal is a deal.

So, any help would be appreciated.
