The IC Berchtesgaden has changed its policy to upgrade RA to suites.
When you book "standard" you get "executive".
This has been made possible by creating a second executive category. Now there is "executive" and "executive fireplace".
The latter is cheaper in summer and considered a one level upgrade for Amb. The "executive" is the same room without fireplace and about 10 euro more expensive during summer and now considered a double upgrade for RA. (Winter vice versa)
They used to give suite upgrades - and suites are the stunning part in this hotel.

Furthermore, I have been informed that advance purchase discouted rates are only available for standard rooms - never for executive.

Just to give an idea what this means in €€ $$:
Standard deluxe --> Executive room. Cost: 149 Euro (Adv Purchase)
Executive fireplace room --> suite. Cost 260 Euro (Best Flex)
