Try it.

in ext_localconf.php

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
    'TYPO3.' . $_EXTKEY,
    'hotels',
    array(
        'Hotel' => 'list,single,display,update,save,preview,edit'
    ),
    // non-cacheable actions
    array(
        'Hotel' => 'list',
    )
);

in ext_tables.php

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
    $_EXTKEY,
    'hotels',
    'list of Hotels'
);

$extensionName  = \TYPO3\CMS\Core\Utility\GeneralUtility::underscoredToUpperCamelCase($_EXTKEY);
$pluginSignature = strtolower($extensionName). '_hotels';


if (TYPO3_MODE === 'BE') {

    /**
     * Registers a Backend Module
     */
    \TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerModule(
        'TYPO3.' . $_EXTKEY,
        'web',   // Make module a submodule of 'web'
        'hotels',   // Submodule key
        '',                     // Position
        array(
            'Hotel' => 'list,single,display,update,save,preview,edit'
        ),
        array(
            'access' => 'user,group',
            'icon'   => 'EXT:' . $_EXTKEY . '/ext_icon.gif',
            'labels' => 'LLL:EXT:' . $_EXTKEY . '/Resources/Private/Language/locallang_hotels.xlf',
        )
    );

}

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addStaticFile($_EXTKEY, 'Configuration/TypoScript', 'Hotels List');
