Here it is from pal,he lives in Pattaya and has been to meetings there only.
Seedy =
1. An air of shabby respectability
2. Furniture not really of any style but ornate appearance
3. Not reflecting good taste nor really bad taste but let us say no
discernible taste.
4. Lacking a sense of unity of design, occasionally flamboyant,
occasionally plain & ordinary
5. A sort of wedding cake style building
6. The appearance of someones ideal of respectability and with royal overtones
I can go on but will leave it at that.
Let me add however generally clean and seems from what little I know
of it quite acceptably administered.
I would add also similar in design but better in operation than that
overlarge room you stayed in the time before last certainly upmarket
from the pile of rubble, painted purple which had several places
around named the same that you stayed at for I think one night.
You could find it perfectly OK as a typical Pattaya place that does
not quite get off the ground in terms of a 3 or whatever star hotel.
